Divide aggregate values by different denominators dependent on column value

[magb621]

Hello, 

I have created a table which aggregates the sum of Units, Call, and Accounts based on Campaign. I'm trying to display a conversion value where the calculation is dependent on the Campaign. 

If the Campaign is Radio, the conversion formula is: Units / Calls

If the Campaign is Print, the conversion formula is: Units / Accounts

It seems that my attempts at the Conversion column evaluate each row and fails because many rows include 0 in the Calls or Accounts column. I'd like to just divide by the aggregated value of Calls or Accounts. Any ideas?

Campaign	Units Sold	Calls	Accounts	Conversion If Radio, Units / Calls If Print, Units / Accounts
Radio	100	200	350	0.5
Print	200	200	1000	0.2

Thank you!

Maggie

I solved this by adding a new column = to sum of calls if the campaign is Print and sum of accounts in the the campaign is Radio. I then used this column as the denominator in my divide by function and used a sum aggregation on the column containing the divide function.
