Well, you can try this


Option Explicit


Enum CustomErr
    LaidEgg = vbObjectError + 100
    UserEaten = vbObjectError + 200
    Paused = vbObjectError + 300
    Cancelled = vbObjectError + 400
End Enum




Sub drv()


    On Error GoTo ErrHandler
    
    Err.Raise UserEaten, "Sub drv", "User Eaten Error"
    
    MsgBox 1 / 0


    Exit Sub
    
ErrHandler:
    GlobalHandler
    Resume Next
End Sub




Sub GlobalHandler()
    Dim E As Long
    
    E = Err.Number - vbObjectError  '   needed to avoid Overflow Error
    
    If (Err.Number < 0) Then
        MsgBox "Custom Error, 'Number' = " & E
        MsgBox Err.Description
    Else
        MsgBox Err.Description
    End If
End Sub
