How to pop up a Macro when the cell in one column is selected-urge

[Guest]

I know how to call a Macro when one cell is selected as below. But this only
works when cell B1 is selected.

But anybody knows how to trigger the macro when any cell in one column is
selected (E.g when cell from B1 to B1000 is selected...) Thanks a lot!

Private Sub Worksheet_Selectionchange(ByVal Target As Range)

If Target.Address = "$B$1" Then
Call OpenCalendar
End If
End Sub

if target.cells.count > 1 then exit sub 'only one cell at a time
if intersect(target, me.range("b1:B1000")) is nothing then
exit sub
end if

is one way.

Thanks Dave. The problem is well solved. The final codes are as below.

Private Sub Worksheet_Selectionchange(ByVal Target As Range)

If Target.Cells.Count > 1 Then Exit Sub 'only one cell at a time

If Intersect(Target, Me.Range("G2:I5000,K2:K5000")) Is Nothing Then
'column G to I & K needs data input

Exit Sub
End If

Call OpenCalendar ' Call the macro to input date by using Calendar

End Sub
