Hi
I would use a the following in the on click event of the button that launches the forms you want to protect.
Dim strPword As String
Dim stDocName As String
stDocName = "Form Name"
strPword = InputBox("Enter Password", "Edit Locked")
If strPword = "" Then
GoTo Exit_command name
End If
If strPword = "your password" Then
DoCmd.OpenForm stDocName, , , ,
End If
Hope it helps
