Code:=IF(OR(A1 = "", B1 = ""), "no", "yes")
Thanks for the quick reply. That doesn't seem to work. That's returning a positive if either cell is non blank. I need it to return a postive only if both cells are non blank. I changed the "OR" in your formula to "AND" but that didn't do anything
=IF(AND(A1="",B1=""),"Both cells are blank","At least one cell is not blank")
=IF(AND(ISBLANK(A1),ISBLANK(B1)),"Both cells are blank","At least one cell is not blank")
