day.  I have grouped by Date.  I can not count the POs due to formula error when using count(): "There must be a group that matches this field."

Example count PO for 3 days.  My report should look like this:

6/24/2008      800
6/25/2008     1000
6/26/2008      950
   Count PO:  3

How I solve this problem?

Thank you!

 create new running total then select the PO feild.

select COUNT (instead of SUM which is default)

 

place this running total in ur report
