**adatshalom**Thought I had this working, but no longer. If you click payment by check option, you get pulldown menus. The calculator is supposed to multiply first pull down by $20 (as shown in calculator value field) and then add to product of second pulldown field by $10. Thus select 2 and select 1 for $50 total. Now it is just showing 3 (2 plus 1).

I was trying to get rid of the default "30" that was showing up (as if it was 1 and 1).
