Fist, thank you for your help.
I have this array formula in Z2:
{=IF(AND((AG2)="S",(AH2)="S"),"Y",IF(OR((AG2)="U", (AH2)="U"),"R",IF(AG2:AN2="S","G","R")))}
but it doesn't work. When it evals the AND and OR portions it works ok but
when S is in AG2:AN2 it doesn't give the result of "G", it stays a "Y".
What
did I do wrong? Also do I have the AND and OR functions written correctly?

Thanks in advance for your help
Joe
