I have a UserForm that is shown when I open a workbook. The UserForm has a
UserName ComboBox, Password TextBox, Login CommandButton, and a Cancel
CommandButton. I only want .Sheets("QUOTE") to Unhide when this particular
user clicks the Login button, how do I do that? This is what I got so far,
but I am getting an Error.

Note: I don't know if this helps but I use this code to Hide all the
worksheets, when I close the workbook.

Private Sub Workbook_BeforeClose(Cancel As Boolean)

Windows("CALCULATOR 11-5-2007.xls").Visible = False

End Sub


Private Sub cmbLogin_Click()

Select Case
Case "Peter Maida"
If tbxPassword = "peterm2" Then
Workbooks("CALCULATOR 11-5-2007.xls").Worksheets.Visible =
xlSheetHidden '<===ERROR ERROR
Sheets("QUOTE").Visible = xlSheetVisible
With Sheets("QUOTE")
.Unprotect Password:="AdTech"
.Range("F3").Value = "Peter Maida Ext. 208"
.Range("F4").Value = "E-mail: "
.Protect Password:="AdTech"
End With
Unload Me
Exit Sub
Else
MsgBox "Try agian.", vbCritical
With tbxPassword
.Value = ""
.SetFocus
End With
End If
End Select

End Sub
