Shared Variable

[klaidlaw]

I am using Crystal Reports 11 release 2

I am tryin to pass a running total from my subreport into my main report and I cannot figure out what I am doing wrong.

In the subreport the running total is in the Group Footer 2a and the shared variable is in Group footer 2b the formula looks like this:
Shared NumberVar ShippedQty;
ShippedQty := {#ShippedQty};

Then everything in the report is suppressed and placed into the details a section of my report.

The formula to call on the subreport is placed in the detail section b and it looks like this:
shared NumberVar ShippedQty := ShippedQty;
ShippedQty;

So I am not quite sure why i keeps returning 0 instead of the correct number. Any help would be apprectiated

You do not need to do this

shared NumberVar ShippedQty := ShippedQty;
ShippedQty;


In the main report it thinks the second shippedQty is a local var and has a value of zero.

When you want to use your shared var simply declare it in your main report formula and always use whileprintingrecords

ie

@yourformula

whileprintingrecords;
Shared NumberVar ShippedQty;

// add your formula using var as required.
