I am trying to write a formula to check 2 cells, which will have "Y" or "N" in them
The logic is as follows:
IF(Criteria A = TRUE), ((Price-Fees)-Postage)
else
IF(Criteria B = True), (Price-Fees)
else
IF(Criteria C = TRUE), ("")

Criteria A
Sold = "Y"
Post = "Y"

Criteria B
Sold = "Y"
Post = "N"

Criteria C
Sold = "N"
Post = "N"

I hope that makes sense!
