We need a modification to ZENCART
"product filter by attribute and price range 0-7"
([url removed, login to view])
a new module.
It needs to show the products that >0 in the size attributes ONLY. The current module shows products that have stock in any of the attributes.
Scenerio: For Product A: we add 3 Smalls, 3 Mediums, 3 Larges. 3 larges are sold. The next customer looks for all Larges in stock. We don't want them to see product A in the search.
