I have seen your page and I can see that the first two items have the same values in them for the prices. I think I need a little more info about this part:
"When I put the ATC button and the drop down base on item ID it displays all the prices not the prices for the specific item"
When you say you put the ATC and drop down based on the item ID I'm not sure what you mean here.
If you are filtering for a single item that is fine on a details page but is more difficult to do on a page that lists multiple items. Please post back with soem additional info about what you are hoping to accomplish as an end result and also include a copy of this page in a zip archive so it can be examined.
