Password Protecting each sheet for different users

[mcdbennett]

Scenario:
I have 1 workbook with 8 sheets. I only want certain people to be able to access each sheet to modify data. Here is where I am, but I cannot go further. It keeps giving this error Error.jpg marked in red below. Any suggestions?

Private Sub Workbook_aftersave(ByVal Success As Boolean)
    UnprotectSheet
    ThisWorkbook.Saved = True
End Sub
Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean)
    ProtectSheets
End Sub
Private Sub Workbook_Open()
    USERID = Environ("username")
    If USERID <> "Admin" Then ProtectSheets
    UnprotectSheet
End Sub
Private Sub ProtectSheets()
    Sheet1.Protect "password"
    Sheet2.Protect "cadpassword"
    Sheet3.Protect "manpassword"
    Sheet4.Protect "gaypassword"
    Sheet5.Protect "tvcpassword"
    Sheet6.Protect "cdhpassword"
    Sheet7.Protect "grhpassword"
    Sheet8.Protect "tchpassword"
End Sub
Private Sub UnprotectSheet()
    If (USERID = "kalton") Or (USERID = "sheater") Or (USERID = "aavery3") Or (USERID = "thughes") Or (USERID = "mbennett6") Then Sheet1.Unprotect "password"
    If (USERID = "aaben2") Or (USERID = "cjurick") Or (USERID = "tkline") Or (USERID = "mbennett6") Then Sheet2.Unprotect "cadpassword"
    If (USERID = "aaben2") Or (USERID = "cjurick") Or (USERID = "tkline") Or (USERID = "mbennett6") Then Sheet3.Unprotect "manpassword"
    If (USERID = "aaben2") Or (USERID = "jshaw6") Or (USERID = "mbennett6") Then Sheet4.Unprotect "gaypassword"
    If (USERID = "aaben2") Or (USERID = "jshaw6") Or (USERID = "mbennett6") Then Sheet5.Unprotect "tvcpassword"
    If (USERID = "aaben2") Or (USERID = "skillingbeck") Then Sheet6.Unprotect "cdhpassword"
    If (USERID = "aaben2") Or (USERID = "skillingbeck") Then Sheet7.Unprotect "grhpassword"
    If (USERID = "aaben2") Or (USERID = "skillingbeck") Then Sheet8.Unprotect "tchpassword"
    
End Sub
