I make many financial reports and I am having trouble making the percentages
work properly on group total lines. The totals sum up many detail lines and
work fine, but since you can't add the percentages from the detail lines, it
won't work. The detail lines have a percentage and work correctly. I have
been using an average formula currently of the group lines, but you can't
take an average of an average either. But it gets me closer. Does anyone have
a simple solution for a relative intermediate user? Thanks.

Account 1 $100 $25 $75
25%
Account 2 $200 $100 $100
50%

Total $300 $125 $175
42% **
