Selecting a sheet from a range - issue with hidden sheets.

Hi,

I have the below code that selects the sheet from a dropdown list box as selected by the user. How can I modify it so that it unhides hidden sheets first - as at present im just getting an error if the selected sheet is hidden.

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$E$10" Then
Sheets(Range("E10").Value).Select
End If
End Sub
