In Adobe Acrobat XI I need to come up with a sub-total field that references amounts added in seven fields and then subtraction of an amount from one other field:

Something like this:

(Column60001_1 + Column60001_2 + Column60001_3 + Column60001_4 + Column60001_5 + Column60001_6 + Column60001_7) - Column6001A

I have no experience with java calculation scripts.

Thanks,

Jeff
