When you enter the formula, try using Ctrl+Shift+Enter (we call this CSE)
instead of just Enter. This appears to be an array formula, which will
evaluate what you've specified line by line for rows 2:5000, but it won't
work unless you CSE.

I have 2 spreadsheets (sales and returns) that I want to match 4 columns on
and if they match pull the P column from the Returns spreadsheet. I found
some old posts with a formula I tried to follow, but I get 0 everywhere. I
have no idea what this is doing. Can anyone help me? Thanks,


=IF(ISNUMBER(MATCH(1,('2009 Returns'!$A$2:$A$5000=A2)*('2009
Returns'!$B$2:$B$5000=B2)*('2009 Returns'!$C$2:$C$5000=C2)*('2009
Returns'!$D$2:$D$2:$D$5000 =D2),0)),'2009 Returns'!P2,0)
