dynamic select list different prices

Hi.

I have a database with product 1 (Vanilla Cakes) and product 2 (Chocolate Cakes).

Product 1 has 4 sizes - size 1, 2, 3 and 4 with size 1 = $1; size 2 = $2; size 3 = 3$ and size 4 = $4.

Product 2 also has 4 sizes - size 1, 2, 3 and 4 with size 1 = $1.50; size 2 = $3.75; size 3 = 4.90$ and size 4 = $5.

On my results page I now have a repeating region with all the different products in a separate row with their pictures, prices etc. Now instead of having four lines for product 1 and four lines for product 2, I want just one line for product 1 with a select menu where I can choose which size I want and another row for product 2 with the same choices.

I have gone through all the tutorials but I can't seem to find out how to do this. If all the prices are the same I know how to do it or if the sizes increase by a fixed amount I know how to do it but not how to have one product with different sizes and different prices for each size.

Is this possible with the Ecart extension or is this not something that I will not be able to do with Ecart?

Thanks for any help and/or advice.
