Worksheet_Change(Byval Target as Range) [duplicate] - excel

Question

I am trying to run this worksheet change event for two different columns(A) and (I)...
Private Sub Worksheet_Change(ByVal Target As Range)
Dim A As Range, B As Range, Inte As Range, r As Range
Set A = Range("A:A")
Set Inte = Intersect(A, Target)
If Inte Is Nothing Then Exit Sub
Application.EnableEvents = False
For Each r In Inte
r.Offset(0, 1).Value = Date
Next r
Application.EnableEvents = True
End Sub
This event is something i found on this forum. Its purpose is to make it so whenever data is ever entered into column "a" it auto inputs the date into the cell directly right of it. I want this to happen twice on the worksheet. I can't figure out how to change/add to it. I am trying to get it to run the logic for column A and I on my spreadsheet.

Answer 1

Just expand the range you set to the A variable.
Set A = Range("A:A, I:I")
Rewritten as,
Private Sub Worksheet_Change(ByVal Target As Range)
if not intersect(range("A:A, I:I"), target) is nothing then
'add error control
on error goto safe_exit
'don't do anything until you know something has to be done
dim r as range
Application.EnableEvents = False
For Each r In intersect(range("A:A, I:I"), target)
r.Offset(0, 1).Value = Date 'do you want Date or Now?
Next r
end if
safe_exit:
Application.EnableEvents = True
End Sub

edited after OP's comment
expanding on #Jeeped solution, you can avoid looping:
Option Explicit
Private Sub Worksheet_Change(ByVal Target As Range)
Dim rng As Range
Set rng = Intersect(Range("A:A, I:I"), Target) ' define range of interest
If Not rng Is Nothing Then ' check it's not "nothing"
If WorksheetFunction.CountA(rng) = rng.Count Then 'check for all of its cells being not empty
On Error GoTo safe_exit 'add error control
Application.EnableEvents = False 'don't do anything until you know something has to be done
rng.Offset(, 1).Value = Date 'write Date next to all relevant changed cells
End If
End If
safe_exit:
Application.EnableEvents = True
End Sub
