Assign array values to items in a sub report

Hi everyone,

I have a certain group in a main report. For each item in that group i want to store a value in an array variable specific for that item.

Also I Have a sub report placed in the main report and I wanted to display the value for the matching items in the sub report. But the sub report may or may not have the items that correspond to items in the main report.

For example let items A,B and C are in the main report and have values.

If item B doesn't exist in the sub report,ignore the value at index 2 of the array and assign the value at index 3 to item C.

Is it possible to do that?

Thank you
