I have for all my products two variants, one is the size, the other is the color...

Color is an image radiobutton.
Size is a Combobox
The images I show for each color, are the same for every size... size is used only for the buying info...

The image doesn't changes if I choose the color, unless I change the size under the combo.

Is it any way I can edit the source code, for the aspx to show me the color under (lets suppouse) the small size combination?
The closer I've arrived, was to setup the small size as the default selected index... but if a customer clicks on "buy product" without changing the size, he might be buying a wrong product...

Any idea?
(Anyone understood my question? Every day I express myself worst... sorry...)

Thanks everyone.
Regards.
