I need some help with a formula on a report.

The report has a 2 grand total at the bottom of the report, current owed & current paid.

The grand total sum looks like
=Sum([CURRENT OWED])
=Sum([CURRENT PAID])

what formula would I use to figure the % of PAID to OWED

would it be something like?

=SUM(=Sum([CURRENT PAID])/=Sum([CURRENT OWED]))

Thanks Mike
