I need a excel/office 2003 formula to work out =countif(G$3:G$nn,G3) where
'nn' is calculated by another formula in another cell: =M1+COUNTIF(B:B,B3).
Seems like it should be easy but nothing I've tried works.
None of the key words I've tried in Help have helped.
Can someone point me in the right direction please.
