Using reference column # in IF Statement

[tjvols]

A B C D E
1 Bob Sam Tom
2 =if(c3=0," ",row()) 10 0 4
3 0 5 4
4 4 5 8 0
5 5 4 0 0


I want to be able enter "Bob" in A10 and have the reference in the
formula in B2 look to A10 to get the column needed for the
calculation. If I change to A10 to "Sam" the formula would change to
=if(d3=0," ",row(). I also need to be able to copy this formula down
into B3, B4 & B5.

Any help would be greatly appreciated.
Thanks.

Try this:
=IF(OFFSET(B2,0,MATCH($A$10,$C$1:$E$1))=0,"",OFFSET(B2,0,MATCH($A$10,$C$1:$E$1)))

Try this:
=IF(OFFSET(B2,0,MATCH($A$10,$C$1:$E$1))=0,"",OFFSET(B2,0,MATCH($A$10,$C$1:$­E$1)))

That kinda works, but it returns the actual value in the column
selected. I need the row number instead -
ie. if Bob was in A10 the results would be A2 (2), A3 (" "), A4 (4) A5
(5). If Tom was in A10 the results would be A2 (2), A3 (3), A4(" "),
A5 (" ")

Minor change:
=IF(OFFSET(B2,0,MATCH($A$10,$C$1:$E$1))=0,"",MATCH($A$10,$C$1:$­E$1))

I found a solution -
=IF(OFFSET(A3,0,MATCH($A$10,$B$1:$D$1,0))<>0,ROW()," ")

thanks for your help, I never would have figured it out without it.
