Solved: Protection Problems

A few weeks ago I asked for assistance in setting up protection. I have found that I need to modify some cells and now I can't remove the protection. I've taken out the protection line with the password but when I try to unlock the worksheet it still requires a password.
Can someone please explain what is happening and how to correct this. See the code below,
[VBA]
Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)
' Sh.Protect Password:="pass", UserInterfaceOnly:=True
If Target.Cells.Count > 1 Then Exit Sub
If Not Intersect(Target, Sh.Range("B8:O34")) Is Nothing Then
Select Case Target.Value
Case "V.5", "V1" To "V999"
Target.Interior.ColorIndex = 35

Case "PL.5", "PL1" To "PL999"
Target.Interior.ColorIndex = 34

Case "SL.5", "SL1" To "SL999", "FS.5", "FS1" To "FS999"
Target.Interior.ColorIndex = 36

Case "BL.5", "BL1" To "BL999"
Target.Interior.ColorIndex = 36

Case Is = "ML.5", "ML1" To "ML999"
Target.Interior.ColorIndex = 24

Case Else
'No conditions met, so make it normal
Target.Interior.ColorIndex = -4142
End Select
End If
End Sub
[/VBA]
It is very frustrating to be unable to work on your own spreadsheet. Thanks

If the worksheet is protected, you will need to unprotect it. Commenting out the line will not unprotect it. Go to Tools | Protection | Unprotect Worksheet and enter the password.

That is my problem, no matter what I do I can't unprotect, with or without the password, with or without that line commented out.

What do I do now?

Disreguard, apparently the password in the vba code was diffierent from the sheet password. After using different variations of the passwords I normally use I was unable to unprotect it.
Thanks
