Having a difficult time making a product with options

[denverdonate]

I can't seem to figure out how to make a product with options like:

Choose Size (radio buttons to alter price)

Select a size
(+$1) 3x5
(+$2) 5x7
(+$3) 8x10

Now select a paper
(+$1) Glossy
(+$2) Matte

Proceed to Checkout

Do I have to build these in custom fields? When I click custom fields there's a dropdown with options such as boolean, string, etc but I can't make sense of how to make a pricing list there. Any guidance on how to do this would be very appreciated. All week I have been trying to figure it out because it seems so easy but I can't seem to figure it out!

Make a custom field STRING with "Select a size" and so on, and activate the options cart input and cart attribute.

Choose that later in your product tab custom fields.

PPS. Check AH's post below, that plugin works very well.
