I know this answer is out there somewhere...I just can't seem to get any to
work. What I want to do in Sheet1 is lookup cells A1,A2,A3,A4 in Sheet2
cells A1,A2,A3,A4. If it finds a match of all 4 criteria, then return "OK"
otherwise return "NO MATCH". I am very close with variations of Match,
Vlookup, etc....please help!

Thanks in advance!
