Quote talanis Replybullet Topic: Avg formula using summary
    Posted: 20 Sep 2011 at 6:36am

my first column is quantity, the next is extended pricing, in the third column I would like a formula.  ie (extended price/qty)  I have my columns of numbers with a Sum in the Group Footer.  Is there any way I can insert my formula as a 3rd column in the same Group Footer?  I keep getting avgs of the line above my formula.  Any help would be appreciated.  Thanks.

you can create a formula field per row to show the average for the row
table.extended price / table.qty
then insert a summary of this formula field as an average for the group level

7.82973 30.09333
Here are my numbers...
the 7.82973 is 173.82/22.2, the 30.09 is an average from 270.84
I am trying to get the  7.82973 number.  I know I am getting close but my terminology is holding me back.  Sorry.

sum(pricing,groupfield) / sum(quantity,groupfield)

FBlank - thank you for all your suggestions.  I finally got it!!! YEAH!
This is what finally worked...Sum ({Sheet1_.Extended}, {Sheet1_.Company})/Sum ({Sheet1_.Qty}, {Sheet1_.Company}).
