We only want customers to be able to select one of the two grouped products we offer and the qty will always be 1.
Modifying the qty text entry to only be a radio button and make them mutually exclusive in catalog/product/view/type/
tml like this:
<input type="radio" name="super_group[qty]" value="<?php echo $_item->getId() ?>" />
Will it work correctly?
How/where would I determine to set the qty for the selected one to 1.
