How to use an array to retrieve records from a subreport?

[Devaki]

Hi,

I retrieve a set of records for example A B C D from the subreport by passing the parameter from the main report.
If i try to retrieve it to the main report using a shared variable it returns only the last record i.e D How do i make it return all the records i.e A B C D ? I am using Crystal 8.5. The parameter that i am passing is also a group field in the main report

Thanks
