Manipulating Group Summaries

Hi,

Relatively new to Crystal and ran into a little issue while building a new report. I created a Formula field to define "LATE" or "ON-TIME". I used Group Summary to Count the number of items LATE and the number of items ON-TIME.

I would like to achieve 2 things.

1. Calculate the percentage of LATE and ON-TIME and place in separate fields in the report header.
2. Copy the Count of LATE and ON_TIME and place in separate fields in the report header.

I am quickly finding out the group summary in the group footer is not easy to work with. Any help is appreciated.

Thanks,
