Anyone could tell me the way to make a array and then get their values I have understood that I have to do something like this:

<%
'Creating and initializing the array(unidimentional)
Dim MyArray()
Redim MyArray(request.form.count)

for each item in request.form
MyArray = request.form(item)
'keep the values of the previous form
next


'Geting the values from array(fifth elemment in a array) and using the values in a select
select * from x where y = session(MyArray(5))
%>
'Make it like array session type
session(&quot;array1&quot;) = MyArray

Thanks

Almost!

First, you'll need to tell the script engine which array element to put each value into.

dim indexcounter
for each item in request.form
MyArray(indexcounter) = request.form(item)
indexcounter = indexcounter + 1
next

second, since arrays are zero based, to get the fifth element, you'd use an index of 4, not 5.

I'm not sure I understand your problem, but I'll take a guess. If you're trying to access the array directly from the session variable, that's the problem. You need to assign it to another variable in your page.

Assume that on the first page, you've used the code in my previous post. You now have an array called MyArray. You can store the array in a session variable like this:
session(&quot;MyArrayVariable&quot;)=MyArray.

when you want to retrieve the contents, you can't use the session variable directly. You need to copy the contents to another variable:
MyNewArray=session(&quot;MyArrayVariable&quot;)
response.write MyNewArray(1)

Here's a page that shows what I mean:
Code: 
<html><head></head><body>
<% 
dim MyArray(2)
if request.form.count = 0 then
    MyArray(0) = &quot;zero&quot;
    MyArray(1) = &quot;one&quot;
    MyArray(2) = &quot;two&quot;
    session(&quot;MyArrayVariable&quot;) = MyArray
%>
    <form action=&quot;test.asp&quot; method=&quot;post&quot;>
    <input type='hidden' name='junk'>
    <input type='submit' value='submit' >
    </form>
<%
else
    dim NewArray
    dim ArrayMember
    NewArray = session(&quot;MyArrayVariable&quot;)
    if isArray(NewArray) then
        for each ArrayMember in NewArray
            response.write ArrayMember & &quot;<BR>&quot;
        next
    else
        response.write &quot;Session Variable does not contain an array&quot;
    end if
end if
%>
</body>

What I'm saying is:
you cannot directly put/get array values to/from a session variable. You must use an interim variable.

To store an array in a session variable:

1) declare a local variable for your array
dim a(2)

2) populate your array[/color]
a(0)=&quot;0&quot;
a(1)=&quot;1&quot;
a(2)=&quot;2&quot;

3) copy the local variable to a session variable
session(&quot;savedarray&quot;) = a

To retrieve values from an array that was stored in a session variable:

1) declare a local variable
Dim b

2) Copy the array from the session variable to the local variable:
b=session(&quot;savedarray&quot;)

3) Retrieve the individual values from the local variable:
response.write b(0) & &quot;<BR>&quot;
response.write b(1) & &quot;<BR>&quot;
response.write b(2) & &quot;<BR>&quot;
