Need help with Long Formula for compatability with Excel 97-2003!!

Can someone help me!? I have a workbook that has a very long formula in 576 different cells. It is a football picks spreadsheet that tracks points based on winners and losers. It works for all Excel programs after 2003 version, but some of the users that I send it to have the older versions that do not allow as many characters for the formulas, or as many calculations. Here is an example of one cell's formula. Can you help me consolodate it to where it will work in previous versons of Excel?

=IF((B3=Sheet2!$A$2),$I3,IF((B3=Sheet2!$A$3),$I3,IF((B3=Sheet2!$A$4),$I3,IF((B3=Sheet2!$A$5),$I3,IF((B3=Sheet2!$A$6),$I3,IF((B3=Sheet2!$A$7),$I3,IF((B3=Sheet2!$A$8),$I3,IF((B3=Sheet2!$A$9),$I3,IF((B3=Sheet2!$A$10),$I3,IF((B3=Sheet2!$A$11),$I3,IF((B3=Sheet2!$A$12),$I3,IF((B3=Sheet2!$A$13),$I3,IF((B3=Sheet2!$A$14),$I3,IF((B3=Sheet2!$A$15),$I3,IF((B3=Sheet2!$A$16),$I3,IF((B3=Sheet2!$A$17),$I3,IF((B3=Sheet2!$A$18),$I3,IF((B3=Sheet2!$A$19),$I3,IF((B3=Sheet2!$A$20),$I3,IF((B3=Sheet2!$A$21),$I3,IF((B3=Sheet2!$A$22),$I3,IF((B3=Sheet2!$A$23),$I3,IF((B3=Sheet2!$A$24),$I3,IF((B3=Sheet2!$A$25),$I3,IF((B3=Sheet2!$A$26),$I3,IF((B3=Sheet2!$A$27),$I3,IF((B3=Sheet2!$A$28),$I3,IF((B3=Sheet2!$A$29),$I3,IF((B3=Sheet2!$A$30),$I3,IF((B3=Sheet2!$B$2),"W",IF((B3=Sheet2!$B$3),"W",IF((B3=Sheet2!$B$4),"W",IF((B3=Sheet2!$B$5),"W",IF((B3=Sheet2!$B$6),"W",IF((B3=Sheet2!$B$7),"W",IF((B3=Sheet2!$B$8),"W",IF((B3=Sheet2!$B$9),"W",IF((B3=Sheet2!$B$10),"W",IF((B3=Sheet2!$B$11),"W",IF((B3=Sheet2!$B$12),"W",IF((B3=Sheet2!$B$13),"W",IF((B3=Sheet2!$B$14),"W",IF((B3=Sheet2!$B$15),"W",IF((B3=Sheet2!$B$16),"W",IF((B3=Sheet2!$B$17),"W",IF((B3=Sheet2!$B$18),"W",IF((B3=Sheet2!$B$19),"W",IF((B3=Sheet2!$B$20),"W",IF((B3=Sheet2!$B$21),"W",IF((B3=Sheet2!$B$22),"W",IF((B3=Sheet2!$B$23),"W",IF((B3=Sheet2!$B$24),"W",IF((B3=Sheet2!$B$25),"W",IF((B3=Sheet2!$B$26),"W",IF((B3=Sheet2!$B$27),"W",IF((B3=Sheet2!$B$28),"W",IF((B3=Sheet2!$B$29),"W",IF((B3=Sheet2!$B$30),"W",0))))))))))))))))))))))))))))))))))))))))))))))))))))))))))

Thank You!!

change title to get rid of "need help".
but i assume you are trying to match b3 in sheet2 a2:a30 return i3
if not then match b3 in sheet2 b2:b30 and return w
else 0?
if(isnumber(match(b3,Sheet2!$A$2:$A$30,0)),$i3,if(isnumber(match(b3,Sheet2!$B$2:$B$30,0)),"w",0)) should do it

i dont know but post that as a separate question
