Thank you. 

Unfortunately this is a half solution. Yes it give me a report that shows the total, how do I get monthly columns? This report just gives me one long column, with all the sales, and totals. I guess I could run a report for each month, but that seems crazy. 

What I'd like is something like this - 

in 2024

In Jan I sold 2 'A' widgets,3 'B' Widgets and 0 'C' Widgets 

In Feb I sold 3 'A' widgets,5 'B' Widgets and 12 'C' Widgets 

etc...

The Sales by Item Summary is so close - I just want to get rid of some columns....
