Thank you Jasen,
This will work just beautifully, it is so simple and easy. This is exactly what was driving me crazy. It is simple thing and I was going about it in a very complicated way.
Thank you very much for your advise.
One problem still in place though - the selected size from the product_results it is not transferring correctly to the shopping cart. It is always transfers the first value on the list, does matter what value I have selected.
I appreciate your help.
