Default Not sure if I am in the right place.

I need some help with my code. I need a messagebox to show and I know the code is right, but it only works for VB not for Visual Web Developer(2010). Could someone please look at my code to see if I have done something wrong. Thanks

 'Declare variable for the calculations.
        Dim decRoomCharges As Decimal               'Room charges total
        Dim decAddCharges As Decimal                'Additional Charges
