Hi Donald, your formula lacks a pair of parenthesis; try: IF(ISERROR((G2*H2)/F2),"",(G2*H2)/F2) But it would be simpler just to test F2 for being zero, as in: IF(F2<>0,(G2*H20/F2,"") Keep in mind that having your formula put a space in the cell can lead to another kind of error in Excel, if this cell is then used for other calculations. It would be better to put in a zero instead of a space. Best, Wilson At 21:55 18/01/03 -0500, Donald C.
