Ok, so I know how to do this using a back page sheet
=IFS(Sheet2!B1=1234,"GM",Sheet2!B1=2345,"AP",Sheet2!B1=FALSE,"")
But what I ultimately need and can't figure out is how to do this in the same cell. Rather than typing the "PIN" in Sheet2 B1 to input the initial in Sheet 1 M2, I need to be able to type the "PIN" into Sheet 1 M2 and have it change to the initial when I hit enter and leave the cell.
Any ideas?
