Assign *Permissions* based on Users Level...

You already have your Main Menu (Switchboard) but now you don't want your Users to get access to all the Forms and/or you may only want to assign certain *permissions* based on their level.  Here's a technique that will do just that.  You can find another way here.  (Please read all the way thru before implementing!)
Private Sub cmdDelete_Click()

If Forms![frmMainMenu]![txtSecurityID] <> 13 And Forms![frmMainMenu]![txtDelete] = False Then
MsgBox "Please see ADMIN's " & ConcatRelated("ADMINNames", "qryADMINs", "uSecurityID = " & 13) & " to DELETE records!", vbCritical, "Permissions"
Exit Sub
End If

Dim intResp As Integer

intResp = MsgBox("This will remove the record from your system! Are you sure?", vbYesNo + vbExclamation, "Delete")

If intResp = vbYes Then

   Call LogDeletion(Me.txtOrderID, "frmOrders", "Order " & Me.txtOrderID & " has been successfully deleted!")
   MsgBox "Deleted successfully"
End If
End Sub
In your Table where you keep your Users information add whichever fields are missing from your table from the one below.  Note, txtDepartmentID is optional and not needed to implement this module.  (You can name your fields whatever you like, however, make sure you follow that field name change throughout the rest of the code on this page.)

To capture this information I use a New User form where the User enters their First Name, Last Name and eMail Address and the balance is captured via code.  Doing it this way you don't have to pester the User with logging on every time they want to open the database.  Initially, their permission is set to Read Only, to change it to Read/Write you will need an ADMIN.
If you don't already have one, set up tblSecurity, as shown below.  You only need to enter the three entries shown below.  The ones with nothing under sSecurity are not used in this example.  Again, if you already have one under a different name you will need to change he code accordingly.
On your Main Menu (or Switchboard) you will need 6 (six) hidden unbound fields named...
Copy and paste the code between Private Sub Form_Load() and End Sub to the On_Load event of your Main Menu (or Switchboard).  (Reminder, check the field names to make sure they are reflected below if you are not using the ones assigned above.)
frmNewUser available here.
On a Command Button...
On a Forms On_Current event...
Private Sub Form_Current()
On Error Resume Next

     If Forms![frmMainMenu]![txtSecurityID] = 9 Then
       fncLockUnlockControls Me, True
       fncLockUnlockControls Me, False
     End If

End Sub
Private Sub Form_Current()
On Error Resume Next

     If Forms![frmMainMenu]![txtSecurityID] <> 13 And Forms![frmMainMenu]![txtOverride] = False Then
       fncLockUnlockControls Me, True
       fncLockUnlockControls Me, False
     End If

End Sub
You may want to add a Temporary Access button.  This button can be used for several purposes, such as, giving a User temporary ADMIN abilities or with some additional code the ability to delete when that is only reserved for ADMIN's.

To do so, add a command button to your Main Menu (or Switchboard) and name it cmdTemporaryAccess.  You can put whatever image or caption you want on the button.  In the screenshot above it's the command button with the image of a key on it.

Then copy\paste the code between Private Sub cmdTemporaryAccess_Click and End Sub to the On_Click event of the button. 
(Reminder, check the field names to make sure they are reflected below if you are not using the ones assigned above.)
Create a Module, mine is named modUtilities, and copy/paste the IsDeveloper() and ChangeProperty() code shown below into the Module.  Do NOT paste behind the Form these two Functions must be a separate Module.
The difficult I do immediately, the impossible takes a little bit longer.
