I have CR XI and I am having problems with creating a linked subreport.

Specifically:

MainRpt
field_Top -top number
field_A -Number
field_B -String
field_C -Boolean

if field_C = True ==> field_B has a sub-level of data
I need the sub report in the above main rpt to report out
the sub level data.

I created a formula field in the sub_report called sub_level and I
have its value set to "True".

I performed the setup on the subreport link.

Results: If field_top display 5 records with field_C in one row =True...the sub reports outputs field_B's sub level data.

Problem: When field_top displays 5 records with field_C in 2 or more rows =True....the sub reports outputs are blank?

I need help ASAC.

Thanks
