Paste Special

I have the following in my Workbook


Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)
'If you have any worksheet to exclude
If Sh.Name = "Sheet2" Then Exit Sub
With Target
If Len(.Value) Len(Trim(.Value)) Then

MsgBox "You just entered a leading space character in" & vbCrLf & _
" cell " & .Address(0, 0) & "." & vbCrLf & vbCrLf & _
"If you intend to delete the value in that or any cell, " & vbCrLf & _
"please press the Delete button on your keyboard.", 16, " No leading spaces allowed !!"

Application.EnableEvents = False
.Value = Trim(.Value)
Application.EnableEvents = True
End If
End With
End Sub
When I tried to Copy>Paste Special > Formats or Values of more than One row this line highlights


If Len(.Value) Len(Trim(.Value)) Then
That is, if I select C3:Q3, Copy, then select C10:C15 and try to do a Paste Special that is when it gives me an error 13: Type mismatch.

If I just select C10 and do the Paste Special, it's just fine.
