How to summarize and total an alphanumeric column?

[ry1633]

I'm working on a report project in Report Studio where I need to summarize and make totals of a non-numeric column.  How do I do that?  The column in question is a "Category" with alphanumeric text and data in it.      I need to summarize and total each Category.    I have them grouped correctly in Report Studio, but I can't get them to total up for each one.    I try to click Summarize but the "Total" option is grayed-out.

I think I got it to work - or at least very close.  By playing around with the list of footers, adding a count of the Category to the middle list footers, and then adding at TOTAL summary to the bottom-most footer of the report
