Hi there,

I have two different fields, amount pledged and amount paid.  Each field is summed to represent two different totals in my report (please see the attached) What I need to do is calculate the percent UNPAID which is essentially Total Amount Pledged/Total Amount Paid *100 but receive a division by zero error because I am not dividing the summed totals.  I can't figure out how to do this - any help would be greatly appreciated as this is the very last component of my report,

Thank you - Field View Field View

In the formula editor, be sure to choose the sum fields for the appropriate group or report level.  If you are looking at placing this in group level one, find the sum fields for pledge and gl balance for group level one.  If you are looking at doing this at the report level, find the sum fields that say report level.

Generally, the way to get around this is to account for it in a formula:

If
  Total Amount Paid = 0
Then
  0
else
  Total Amount Pleged % Total Amount Paid

As joeyw says, in your formula editor, make sure you choose the right summary values.

FYI, if you use hte % operator, you don't need to do the / and *100.  

You will still need to account for division by zero using logic, such as in the example above.

I really think this should be a split.  My comment was simply to provide assistance to the original comment.
