I have this code in "ThisWorkbook":

Option Explicit
Public sShName As String
Public bPwrdEntrd As Boolean
Public sPwrd As String
Private Sub Workbook_SheetChange(ByVal wsShName As Object, ByVal
Target As Range)

If Right(wsShName.Name, 7) < "Monthly" Then 'ignore these sheeets
Select Case wsShName.Name
Case "(Code Key)" 'Excluded sheets
Exit Sub

Case Else 'if password hasn't been entered yet, then ask
for password
If bPwrdEntrd = False Then

Call PasswordEntry
End If
End Select
End If

End Sub

Sub PasswordEntry()
Dim rFoundShName As Range
Dim rShNames As Range
Dim wsPwrdNames As Worksheet
'Dim sPwrd As String

Set wsPwrdNames = ThisWorkbook.Sheets("sheet1")
Set rShNames = wsPwrdNames.Range("A1:A8")
wsPwrdNames.Visible = True

ufPwrdEntry.Show

Set rFoundShName = rShNames.Find(ActiveSheet.Name, _
LookIn:=xlValues, _
LookAt:=xlWhole)

If sPwrd = rFoundShName.Offset(1, 0).Value Then
bPwrdEntrd = True

End If
wsPwrdNames.Visible = False

End Sub

And this code in the userform (ufPwrdEntry):

Sub cbOK_Click()
sPwrd = ufPwrdEntry.tbPwrdEntry.Value <----VARIABLE NOT DEFINED ERROR
If sPwrd = "" Then
MsgBox "Please enter the password to access this worksheet.",
vbOKCancel
End If
End Sub

I'm getting a "Variable not defined" error on the noted line.

I checked in Walkenbach, which says, "To make a variable available to
all the procedures in all the VBA modules in a project, declare the
variable at the module at the module level by using the "Public"
keyword rather than "Dim"."

So is a userform not counted as part of the project? Why isn't this
varible being recognized?

Thanks!
