LEn,

That formula will error out if you try to copy it to column B, and your
syntax is wrong, anyway.

Try it like this to match column H:

Dim rng2 As Range
Range("J1").FormulaArray = "=IF(ISERROR(G1-H1),G1,(G1-H1))"
Set rng2 = Range("J2", Cells(Rows.Count, 8).End(xlUp).Offset(1, 2))
MsgBox rng2.Address
Range("J1").Copy rng2

Hi ,

It seem that the modified VBA code ( ie suggested by OssieMac ) below
can not work when it copies down excel array formula for this
scenario, does it miss out any code ??
Please help, thanks


Sub test()
Dim rng2 As Range
Range("J1").FormulaArray = "=IF(ISERROR(G1-H1),G1,(G1-H1))"
Set rng2 = Range(Cells(1, 2), Cells(Rows.Count, 2).End(xlUp))
Set rng2 = rng2.Offset(0, 8) Cells(1, 10).Copy Destination:=rng2
End Sub
