I have my website done except for my order form page and really need some help.

I will use an example to try to explain what the problem is.

Lets say I want to sell plates. But I dont want to sell just any old plates. My plates come in 4 different sizes, 4 different designs and all different colors.

So I made an order form that had all the customers info and drop down boxes to make all the different selections but then I went to paypal and what I figured out was that paypal would want to assign a different "buy me" button to each of the different selections. So if you do the math that is:

4 different sizes x 4 different designs x 8 different colors.

That is way to many buttons.

So I changed my form and made a table that would look like this:

Design 1
Small - $5.00
Medium - $10.00
Large - $15.00
Extra Large - $20.00

Problem with this format is now there is no color choice. I went back to paypal and found that they have a selection to pick up to 10 colors but that would mean customers would be picking a color after they check out and I think my customers should be able to pick their color before purchasing a plate.

Like I said my website is done except for this order form and I hate to hire a pro just to do 1 page for me, so if anyone could help me it would be greatly appreciated.
