hi everyone

 

I performed a summary using the SUM function.

These summaries are grouped by a particular field.

 

I need to identify the maximum of these grouped summaries. So it tried to perform a summary on these grouped summaries, but it's not possible

 

This seem like a simple task, but i've tried and tried again and have had no luck.

 

I am using Crystal Reports 10

 

Any suggestions would be appreciated.

 

thanks

Andy
