Hi,

I have spreadsheet with long list import every month columns "E" = subtotal "F" = GST, "G" = QST , "H"= HST and  fifth column "J" total

how can I modify the code below to add those columns above and put the total in column "J",

here is the code:

Sub SumByArray()
Dim arrayColA As Variant, arrayColB As Variant, arrayColC As Variant 'must be declared as variants.
Dim iArrayIndex As Long, dblArrayItemColA As Double, dblArrayItemColB As Double, dblArrayItemColC As Double

arrayColA = Sheet1.Range("E2:E1000")
arrayColB = Sheet1.Range("F2:F1000")
arrayColC = Sheet1.Range("J2:J1000")

For iArrayIndex = 1 To 10
dblArrayItemColA = arrayColA(iArrayIndex, 1)
dblArrayItemColB = arrayColB(iArrayIndex, 1)
dblArrayItemColJ = dblArrayItemColA + dblArrayItemColB
arrayColC(iArrayIndex, 1) = dblArrayItemColC
Next iArrayIndex

Sheet1.Range("J2:J1000") = arrayColC
End Sub

I tried but doesn't work just put "0" values in column "J"

than you,
