How to format a subreport in main report

[Mackooo]

hi Guys,

I would like to see a sub report to be formated in my main report. As I have filtered records for my sub report based on a linked field with my main report.

Now I can format the subreport on its own with constant number of lines printed with a funtion called in print event of the header and detail section as shown
GROUP HEADER: OnPrint Event
=SetCount([Reports]![Rpt How To Print a Constant Number of Lines Per Group])
DETAIL SECTION:OnPrint event
=PrintLines([Reports]![Rpt How To Print a Constant Number of Lines Per Group],[TotGrp])

Where setCount and Printlines are function

Now I would like to call this form in subreport, when I do that I am getting an error and I not sure how to call this in my main report which is REPORT1.

Please help me how to call these references in my main report.

Thanks in advance.
