Hello all!

I am trying to figure out how to plug this formula into excel so it will do the calculations for me:

Three Skinfold Sites (Chest, Abdominal, and Thigh sites from above, SUM3 is the sum of these sites in mm)
Bone Density =
1.1093800 - (0.0008267 * SUM3) + (0.0000016 * SUM3) -
(0.0002574 * Age)
Body Fat Percentage =
[(4.95/Bone Density) - 4.5] 100
I have a basic working knowledge of Excel, but this is just plain nuts!

Any help is MUCH appreciated!!!
