Basically, I have a price quoter that I am working on. The way it should work is:
The user selects the quantity of cards from the combo box.
In the textfield a price displays once selected. (i.e. 100 = $8.95).
(I have this segment working already.)
Next the user selects whether they need both sides of the card printed on or not.
Updated price displays. (i.e. 100 + both sides = $11.95)
Next comes the delivery timeframe (i.e. 100 + both + two days = 38.95)
And finally whether they need us to design their card or not (100 + both + 2 days + yes = 53.95)

I've been working at this for awhile now, and have determined the best way to go about this is to have if statements add values to the initial value. (i.e. 100 = 8.95, both = +3, two = +27, yes = +15, total =53.95)
The sides and delivery values depends on the selected quantity.

Any and all help is greatly appreciated. Here is the code:
