OScommerce site fixes

[login to view URL] you select a Manufacturer from the list on the left column, in the product listing, for items that have special pricing, it shows them with two Add to cart buttons, also one of the buttons if for a different product all together, This would need to be fixed where it does not show the extra add to cart button from another product when special prices are used. 2. When you use the search function for keywords, it pulls up the products properly, but the product description is blank. 3.

It could be possible that is is just an edited specials module. My site is [login to view URL] if you would like to take a look at the issues.
