I read the manual, but doesn't seem to address the situation wherein:
the user wants to buy different color options of a single product, like 3 red and 2 blue shirts, that
is 5 of the same item.

can someone please advise how to set up? i set up as checkboxes (rather than radio buttons) but it seems confusing to check off them both but still send a quantity of one ...?!

big thanks for help on this
