I'm trying to come up with a formula to help calculate the individual wall sq. ft. of each room.  so far I have figured out how to do this, but when different floor to floor heights are involved I can't seem to come up with the correct formula.Perimeter * 9'0".....works, but some floors are 8"0"so I need the formula to contain more than this and filter through the feild "Level", I thought the formula would be...Perimeter * IF ( Level = lower plan, 9'1", IF ( Level = main plan, 8'1", IF ( Level = upper plan, 8'1"))

if anyone can help me it would be greatly appreciated.

p.s. it's in a room schedule, and the feilds are name, number, level, area, perimeter, floor finish, wall finish, ceiling finish, wall sq.ft.
