Hi, I think I might be doing something wrong. I am using Visual Web Developer 2010. I am trying to get a error message to pop up but the program keeps saying that 'Show is not a member of Messagebox' and I really don't know what to do. Here is the code below. I would really like if someone could point me in the right direction, please. Then error message code is at the bottom, Thanks.

    Dim decAddCharges As Decimal                'Additional Charges
    Dim decSubtotal As Decimal                  'Subtotal

    Dim decTotal As Decimal                     'Total of all charges
    Const decTAX_RATE As Decimal = 0.08D        'Tax Rate. Consts CANNOT be changed by a programming statment

    Try
        'Calculate and display the room charges.
