Hidding and unhidding objects using VBA

Hello,

I'm using the following code to hide and unhide certain tables, queries, forms & modules from the user to prevent them from applying any changes. the code is working fine in terms of getting the job done, but I get  a run-time error 49: Bad DLL calling convention
Where is the issue

Option Compare Database
Option Explicit
 
Public Function HideContactDBTables(Optional strText As String)
    ' Call HideContactDBTables("H")   - To Hide
    ' Call HideContactDBTables("S")   - To Show
    
    Dim intCounter As Integer
    Dim intSetAs As Integer
    Dim bolSetAs As Boolean
    
    'Debug.Print UCase(strText)
    
    If UCase(strText) = "H" Then
        intSetAs = dbHiddenObject
        bolSetAs = True
    Else
        intSetAs = 0
        bolSetAs = False
