Thanks LauraAB,

My issues isn't adding the subtotals themselves, but the subtotal itself only adds everything below the last subtotal (I do currently have subtotal in my list of items).  This is great for most of the invoice, but at the bottom of the invoice I would like to have an overall subtotal for the whole invoice, meaning a subtotal of only the subtotals, not every line in the invoice.  I guess I wasn't clear enough, my apologies.  BRC gave an answer but didn't explain how to get the subtotal to work to add the subtotals, I haven't figured that part out. 

Thanks in Advance,

Andrea
