Hey everyone,

I am designing a shopping cart for a pizza store and I can store regular items
that have no customization like a drink, pasta dish, etc.   I am stoing this
using the usual arrays and structures in which I have the structures holding
the ProductID, Price, Quantity, etc.  But now for a pizza the trouble I am
having is when a customer order a Pizza they need to be able to customize:

Toppings and how they would like the toppings like Half, Full, Double, etc.  I
will give an example below but I can't quite get my head around how to store
such a thing.

For example user clicks on the Pizza they want to order and they get these
choices via checkboxes:

Pizza with Cheese:

Pepperoni : (NONE, 1st HALF, 2nd HALF, FULL, DOUBLE)
Sausage : (NONE,1st HALF, 2nd HALF, FULL, DOUBLE)
Extra Cheese : (NONE,1st HALF, 2nd HALF, FULL, DOUBLE)
Mushrooms : (NONE,1st HALF, 2nd HALF, FULL, DOUBLE)

Now before my array and structure is built to handle storing the like Pizza
with Cheese, Quantity, Price but this kind of customization I am not sure how
will I store what each pizza has.

I am using this example sample that I saw for CDs:

[i]MyCart = ArrayNew(1);

        OneCD = StructNew();
        OneCD.Title = "Cookin at the Plugged Nickel";
        OneCD.Artist = "Miles Davis";
        OneCD.Genre = "Jazz";
        OneCD.Cost = "15.00";
        OneCD.Quantity = "1";

    AddIt = ArrayAppend(MyCart, OneCD);
   
        AnotherCD = StructNew();
        AnotherCD.Title = "Lady in Satin";
        AnotherCD.Atrist = "Billie Holiday";
        AnotherCD.Genre = "Blues";
        AnotherCD.Cost = "14.00";
        AnotherCD.Quantity = "2";
       
    AddIt = ArrayAppend(MyCart, AnotherCD);
[/i]

So the question is really what do I use as the StructKey? is it the topping
itself like [b]Pepperoni[/b] or is it more like the Type like [b]1st HALF, 2nd
HALF, FULL[/b]?

Thanks
