Sub Routine in a Function

[captain15]

I am trying to program a promo code to give a 5% discount to customers entering the code. My problem is that it is within a shopping cart that is already a part of a larger function. Whenever I try to program my subroutine it errors out saying that you cannot have a sub within a method.
What can I do?

Put the new sub outside the method (sub or function) you need to call if from.

You probably have something like:

Public Class Cart
  Private Sub ShoppingCart()
     ...code
  End Sub
End Class

and you're probably trying to put your new sub or function within that. It needs to be outside:

Public Class Cart
  Private Sub ShoppingCart()
     ...code
  End Sub
  Private Sub CalculateDiscount()
    ...code
  End Sub
End Class

This is what I actually have for getting the totals in the Checkout box:

Function GetItemTotal() As Decimal

Dim decRunningTotal As Decimal

If Not objDT is Nothing Then
For Each objDR In objDT.Rows
decRunningTotal += (objDR("Item Total"))
Next
Else
decRunningTotal = "0.00"
End If

Return decRunningTotal

End Function


I have created the following comparator to check for the promo code:

<asp:CompareValidator runat="server" ErrorMessage="" id="CompareValidator1" ControlToValidate="TextBoxPromo" ValueToCompare="BNOV12">
</asp:CompareValidator>
<asp:TextBox runat="server" id="TextBoxPromo"></asp:TextBox>

Now how do I change the function to tell it that if CompareValidator1 is correct to give a 5% dicaount on decRunningTotal?

Thanks,
