I have data in E7 and in H7. Depending on which data they want to go with I
need a formula to make a substration. If they select in L8 that they want the
50% program then in another cell I need the result of E7-M7. If they select
in L8 that they want the 0% program then in another cell I need the result of
H7-M7. No other options available.

My attempt was the following but I got FALSE....I need the differences:
=IF(L8="50%",(E8-M8),IF(L8="0%",(H8-M8),0))

Can you help???

Thanks.
