I'm having troubles export the correct Item Sales summary report.

[SummerLakes]

I'm having troubles exporting an Item Sales summary report that lists the quantity of each item sold by payment method.  I can view the individual quantities in the detail report, but it is not listed by payment method.  I used to be run these reports no problem last December, but something has changed.  I tried customizing my report and it still didn't give me the quantity.  

I appreciate your help!
