An Excel formula?

[bex77]

Do you know Excel? I need help!

I need an Excel formula. I can make it work on paper, but Excel won't take it. It may be something simple, like a missing comma or paren, or I might be totally off. I used to be an ace, but my Excel foo has been rusting for awhile.

Here's the scoop.

I have two columns of data (A and B).

If they are the same, I want C to zero.
If A is higher, I want a 1.
If B is higher, I want a 2.

What formula do I put in C?

A B C
4 2 1
4 4 0
4 6 2

Here is what I tried:
=IF(A-B=0,0,=IF(A>B,1,2))
OR
=IF(A-B=0,0,(=IF(A>B,1,2)))

Excel doesn't like either one. I even tried the "function entering" wizard, to no avail.

Then I tried making two columns, trying to get the two clauses then compare them in a third. Didn't get very far on that front.

If anyone has a clue, I'd appreciate it.

Thanks!
