Limit User From Accessing A Specific Form

I am having a problem restricting a user from a certain form.
I have a module that detects if a user or admin based on the roles entered in the employees table.

If their windows login is not listed in the employees table, they will not be able to view any of the forms.

Here's my problem, I want the users to access the switchboard, but they should not be able to get into the reporting button.

here's my code:
If LOAStatusbtn.Caption = "View Report" _
And Not admin _
Then
'useraccess denied because not an admin
error_text = "You do not have privileges to access this screen." & vbCr & "Please contact an administrator"
MsgBox error_text, , "No Privileges"

End If

If they click on LOAStatusbtn and their role is not admin, then a message should pop up.

I searched the forum and could not find anything similar to this.

Thank you,
