I have three columns: Column A has a list of account numbers. Column B has a dollar amount. In column F, I have a list of accounts that I want to exclude. In Column C, I want to enter a formula that will look at the value in Column A, see if that account number is in Column F, and if it is NOT, then enter the amount in column B into column C. If the account number IS in Column F, then I want the cell in Column C to be blank. I cannot figure this out. It is something like IF(A2<$F$2:$F$21,B2,0) except you can't say "does not equal a range." I don't know the right way to say, "is not found in that range" in Excelspeak.

Can anyone help?
