Counting number of rows displayed after group filtering is applied

Hi,

I need to display the # of rows in my page footer or table footer  for specific types after group filtering is applied. 

Let me give you an example:

I'm trying to show the highlighted in red (not neccessarily in the table footer, could be in the page footer, etc.) and I can't.

I have tried the solutions offered on similar threads, no luck:

• I can't use CountRows("Group") because table footer is outside of the Group.
• I can't use count (reportItems("textbox38").Value) in the page footer (where textbox38 is the claim# field in the group footer row) becaue I keep getting this error: Input string was not in correct format.

Any solutions/hints will be much appreciated.

Thanks!
