checkbox to switch between discount and no discount on form

I am very very new to access and have bludgeoned my way through making an invoiceing system for our workshop but cannot work out how to do this last bit which I assume would be in vb in the way of an IF statement.
On the form there are 5 text boxes:

Total (Ex-Tax): =OrdersSF.Form!txtTotal
              GST:  =[txtTotal]*0.1
   Order Total:  =[txtSalesTax]+[txtTotal]
Discount 10%:
 Invoice Total:  =[txtOrderTotal]-[txtDiscount]

On the form beside the Discount 10% entry is a checkbox and I would like it to display a 10% discount from the order total when checked and retotal the amount to the Invoice total, and when unchecked put a 0 discount in the discount and display the order total in the invoice total without the discount removed.
As I said I am not really sure as to what needs to be done be it a new query or code but any help would be great.
I hope I have explained what I need well enough to get some help on this.
Thanx

    create you checkbox called chkDiscount and set its default value to False, create your txtDiscount and set it default value to 0
    on the event for the checkboxs add this code:-

    Private Sub chkDiscount_Click()
    Dim curTax As Currency
    Dim curTotal As Currency
    If Me.chkDiscount = True Then
        curTax = Me.txtSalesTax
        curTotal = Me.txtTotal
        Me.txtDiscount = (curTax + curTotal) * 0.1
    Else
        Me.txtDiscount = 0
    End If
    End Sub
