I have a Crystal Report that displays basic data about a trade. I
inserted a subreport that displays volumes by month. The subreport
and the report collide - they overwrite each other.

The subreport could be one line or 20. I would like the rest of
the report to continue where ever the subreport finishes.

where did u place ur subreport? r ur details and subreport in same section

u can create a separate section for ur sub-report

is this a question or suggestion
