I have this nested IF formula that does not work, a constant keeps the formula from working. Then to work around the constant I tried an Index lookup as well that does not work.
Col S is typed in to designate a type of steel I need the weight per foot or square foot to be calculated.
W = Qty
Y =Thickness or wt per foot
Z = short side of steel
AA = long side of steel
AB = length of steel

Do I have all these arguments nested correctly? As I copy down the formula the rows change to correspond with the type of steel with dimensions is listed
If I use an Index/Vlookup formula how do I tell the formula to change to the corresponding row (some kind of wildcard for each row copied down).



=IF(S25=2,(Y25*Z25)+(AA25-Y25)*Y25*3.4032,0,IF(S25=3,(Z25*AA25*3.4032),0,IF(S25=4,(Y25*(AB25/12)*W25,0,IF(S25=5(Y25*AB25/12*W25,0,IF(S25=6,(Y25*(Z25*AA25/144)*W25,0,IF(S25=7,(Y25*(Z25*AA25/144)*W25,0,IF(S25=8,(Y25*(Z25*AA25/144)*W25,0,IF(S25=9,(Y25*Z25*3.4032,0,IF(S25=12,(Y25*Z25*ZZ25*.2836,0,IF(S25=13(Y25*Z25*AA25*.2836,0,IF(S25=14,(Y25*(Z25-Y25)*3.4032)+(Y25*AA25)*3.4032,0,IF(S25=16,(Z25-Y25)*Y25*4*.283,0)

I've added the ending parentheses, then tried copy and pasting your answer, still no joy.
I did see and corrected one typo, IF(S25=12 the ZZ25 should be Z25.
What am I missing?

There were too many parentheses to handle -

Try this and must check the accuracy of formula and results for all conditions -

Excel Formula:
=IF(S25=2,(Y25*Z25)+(AA25-Y25)*Y25*3.4032,
IF(S25=3,Z25*AA25*3.4032,
IF(S25=4,Y25*(AB25/12)*W25,
IF(S25=5,Y25*(AB25/12)*W25,
IF(S25=6,Y25*(Z25*AA25/144)*W25,
IF(S25=7,Y25*(Z25*AA25/144)*W25,
IF(S25=8,Y25*(Z25*AA25/144)*W25,
IF(S25=9,Y25*Z25*3.4032,
IF(S25=12,Y25*Z25*Z25*0.2836,
IF(S25=13,Y25*Z25*AA25*0.2836,
IF(S25=14,(Y25*(Z25-Y25)*3.4032)+(Y25*AA25)*3.4032,
IF(S25=16,(Z25-Y25)*Y25*4*0.283,0))))))))))))

Are you saying to copy and paste as is with the line breaks, that puts each line in the cell below my intended cell?

You can do that. It's a good practice to do so when you have large formulae. This way you can easily look for corrections and errors. More significantly it becomes easy to understand at some later stage, if the need be.

The line breaks are within the same cell only

Just in case you are convenient with one line formula. It's exactly the same as above in #4

Excel Formula:
=IF(S25=2,(Y25*Z25)+(AA25-Y25)*Y25*3.4032,IF(S25=3,Z25*AA25*3.4032,IF(S25=4,Y25*(AB25/12)*W25,IF(S25=5,Y25*(AB25/12)*W25,IF(S25=6,Y25*(Z25*AA25/144)*W25,IF(S25=7,Y25*(Z25*AA25/144)*W25,IF(S25=8,Y25*(Z25*AA25/144)*W25,IF(S25=9,Y25*Z25*3.4032,IF(S25=12,Y25*Z25*Z25*0.2836,IF(S25=13,Y25*Z25*AA25*0.2836,IF(S25=14,(Y25*(Z25-Y25)*3.4032)+(Y25*AA25)*3.4032,IF(S25=16,(Z25-Y25)*Y25*4*0.283,0))))))))))))
