Hello,

I use the left, mid and right function to parse this string but am not getting it accurate. This is the data from the field: can you help with formula?

Original: ABCDEFGHIJKLML - 12345678 - HelloWorld

The output should look like this without the word "Original" and the "-"

ABCDEFGHIJKLML
12345678
HelloWorld


 
stringvar x := {table.field};
stringvar x := "Original: ABCDEFGHIJKLML - 12345678 - HelloWorld";
stringvar array y := split(x,":");
stringvar array z := split(y[2],"-");
stringvar elem1 := "";
stringvar elem2 := "";
stringvar elem3 := "";

Then add one of the following to the end of the above formula in each of three separate formulas:

if ubound(z) >= 1 then
elem1 := trim(z[1]); //for first element

if ubound(z) >= 2 then
elem2 := trim(z[2]); //for second element

if ubound(z) >= 3 then
elem3 := trim(z[3]); //for third element

Hi LB,
thanks for your help.
In your formula, is it possible to not hardcode it, because the field is in that format but not necessarily those values

stringvar x := "Original: ABCDEFGHIJKLML - 12345678 - HelloWorld";
 
Sorry, I forgot to remove that line, which was just for testing. Should be:

stringvar x := {table.field};
stringvar array y := split(x,":");
stringvar array z := split(y[2],"-");
stringvar elem1 := "";
stringvar elem2 := "";
stringvar elem3 := "";

Then add one of the following to the end of the above formula in each of three separate formulas:

if ubound(z) >= 1 then
elem1 := trim(z[1]); //for first element

if ubound(z) >= 2 then
elem2 := trim(z[2]); //for second element

if ubound(z) >= 3 then
elem3 := trim(z[3]); //for third element

The error I get is: a subscript must be between 1 and the size of the array and it highlights

stringvar array z := split(y[2],"-");

in the formula.
 
The formula assumes that the field always starts with "Original: ". It obviously doesn't, so now you need to provide all the possible variations of what the field can look like.

Hi LB,
the field always starts with "Original". is correct.

my 3 formula fields look like this:
1.

stringvar x := {table.field};
stringvar array y := split(x,":");
stringvar array z := split(y[2],"-");
stringvar elem1 := "";
stringvar elem2 := "";
stringvar elem3 := "";
if ubound(z) >= 1 then
elem1 := trim(z[1]); //for first element


stringvar x := {table.field};
stringvar array y := split(x,":");
stringvar array z := split(y[2],"-");
stringvar elem1 := "";
stringvar elem2 := "";
stringvar elem3 := "";
if ubound(z) >= 2 then
elem2 := trim(z[2]); //for second element

stringvar x := {table.field};
stringvar array y := split(x,":");
stringvar array z := split(y[2],"-");
stringvar elem1 := "";
stringvar elem2 := "";
stringvar elem3 := "";
if ubound(z) >= 3 then
elem3 := trim(z[3]); //for third element

Can you tell me how i can correct this?

Hi Lb,

The field always begins with "Original:" but anything after that may be different

See example:

Original: ABCDEFGHIJKLML - 12345678 - HelloWorld
Original: ABCDEFGDG - 2343423 - Hello
Original: AB - 3434434434 - World

Thanks again
 
If the field always contains a ":" the formula would work. I'm guessing it might be null.

stringvar x := {table.field};
stringvar array y := split(x,":");
if isnull({table.field}) or
ubound(y) = 1 then
{table.field} else
(
stringvar array z := split(y[2],"-");
stringvar elem1 := "";
stringvar elem2 := "";
stringvar elem3 := "";
if ubound(z) >= 1 then
elem1 := trim(z[1]);
if ubound(z) >= 2 then
elem2 := trim(z[2]);
if ubound(z) >= 3 then
elem3 := trim(z[3]);
elem3 //for element 3--change for other formulas
)

Hi LB
this is what i have for the first formula field
and is throwing me an error:


higlighting unbound(y) : a number, currency amount, boolean, date time , date time or string is expected here



stringvar x := {table.field};
stringvar array y := split(x,":");
if isnull({table.field}) or
ubound(y) = 1 then
{table.field} else
(
stringvar array z := split(y[2],"-");
stringvar elem1 := "";
stringvar elem2 := "";
stringvar elem3 := "";
if ubound(z) >= 1 then
elem1 := trim(z[1]);
 
here are my three formulas:

1st formula:

stringvar x:= {Object.Name};
stringvar array y := split(x,":");
if isnull({Object.Name}) or
unbound(y) = 1 then
{Object.Name} else
(
stringvar array z := split(y[2],"-");
stringvar elem1 :="";
stringvar elem2 :="";
stringvar elem3 :="";

if unbound(z) > = 1 then
elem1 :=trim(z[1]);

---------------------------------
2nd formula:

stringvar x:= {Object.region};
stringvar array y := split(x,":");
if isnull({Object.region}) or
unbound(y) = 1 then
{Object.Name} else
(
stringvar array z := split(y[2],"-");
stringvar elem1 :="";
stringvar elem2 :="";
stringvar elem3 :="";

if unbound(z) > = 2 then
elem2 :=trim(z[2]);

-----------------------------------
3rd formula:

stringvar x:= {Object.address};
stringvar array y := split(x,":");
if isnull({Object.address}) or
unbound(y) = 1 then
{Object.Name} else
(
stringvar array z := split(y[2],"-");
stringvar elem1 :="";
stringvar elem2 :="";
stringvar elem3 :="";

if unbound(z) > = 3 then
elem3 :=trim(z[3]);
 
You are showing three different fields here. Why? You should be using the one field that starts: "Original:". You need to check each field and see what it returns when placed in the detail section.

You are also mistakenly using "unbound"--the function is:

ubound

If you are going to use different fields with the formula, you should change ALL variables to start with "local", as in:

local stringvar x;

Hi LB you are right, my mistake:

here is the revised formulas:
1)
stringvar x:= {Objects.Address};
stringvar array y := split(x,":");
if isnull({Objects.Address}) or
ubound(y) = 1 then
{Objects.Address} else
(
stringvar array z := split(y[2],"-");
stringvar elem1 :="";
stringvar elem2 :="";
stringvar elem3 :="";

if ubound(z) >= 1 then
elem1 :=trim(z[1]);
)

-------------------------------

2.

stringvar x:= {Objects.Address};
stringvar array y := split(x,":");
if isnull({Objects.Address}) or
ubound(y) = 1 then
{Objects.Address} else
(
stringvar array z := split(y[2],"-");
stringvar elem1 :="";
stringvar elem2 :="";
stringvar elem3 :="";

if ubound(z) >= 2 then
elem2 :=trim(z[2]);
)

--------------------
3)

stringvar x:= {Objects.Address};
stringvar array y := split(x,":");
if isnull({Objects.Address}) or
ubound(y) = 1 then
{Objects.Address} else
(
stringvar array z := split(y[2],"-");
stringvar elem1 :="";
stringvar elem2 :="";
stringvar elem3 :="";

if ubound(z) >=3 then
elem3 :=trim(z[3]);
)
 
when running the report:

the error is produced:

stringvar array z := split(y[2],"-");

a subscript must be between 1 and the size of the array
 
I guess you can check for blanks also in each formula as in:

stringvar x:= {Objects.Address};
stringvar array y := split(x,":");
if isnull({Objects.Address}) or
[red]trim({Objects.Address}) = "" or [/red]
ubound(y) = 1 then
{Objects.Address} else
(
stringvar array z := split(y[2],"-");
stringvar elem1 :="";
stringvar elem2 :="";
stringvar elem3 :="";

if ubound(z) >=3 then
elem3 :=trim(z[3]);
)
