I think there is something easy I'm missing with this. I was testing to see if what I wanted would work before adding a bunch of sheets.
I took 2 sheets, I wanted to report Sales and boxes for each project in the same report.
When I only enter one of the 2 items in the "What" the report will generate and include that one value - tested with both items, same result.
When I try to run it with both in the "What" column I get an error message "you must select at least one criteria" - I thought I was selecting 2 so don't understand the error.
