Overflow error on worksheet_selectionchange when counting selected cells

Hi Spritz,

I couldn't duplicate your error probably because I am using Excel 2003. When I selected top left, the count was 16,777,216. Yours is going to be a lot larger using Excel 2010 which may overflow the long integer variable type.

Try one of the following:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)

  Dim iCellCount As Long
  
  On Error Resume Next
  iCellCount = Target.Cells.Count
  On Error GoTo 0

  If iCellCount = 5 And Not Intersect(Target, Range("W5")) Is Nothing Then
    Call frmcalendar.displayin(Range("W5"))
  End If
  
End Sub

Private Sub Worksheet_SelectionChange(ByVal Target As Range)

  Dim iCellCount As Long
  
  On Error Resume Next
  iCellCount = Target.Cells.Count
  If Err.Number <> 0 Then
    On Error GoTo 0
    Exit Sub
  End If
  On Error GoTo 0

  If iCellCount = 5 And Not Intersect(Target, Range("W5")) Is Nothing Then
    Call frmcalendar.displayin(Range("W5"))
  End If
  
End Sub
