Add to Cart in ViewCategories.asp

Does anyone know how to add the "add to cart" buttons to each product by the "more details" link area in the category pages before actually going to the product pages.

I don't need the qty box, just the add to cart button which will add a default number (1) of that item to their cart.

I downloaded the file which is found on the developers page which talks about putting an add to cart button anywhere: http://www.earlyimpact.com/productcart/support/developers.as p
But I don't know what I am supposed to do with it because there isn't a read-me file included. :(

I would like my category pages:
http://www.fidjiti.com/shop/pc/viewCategories.asp?idCategory =311
to have the add to cart button like this one below:
http://www.thesimpleleaf.com/ec/pc/viewcat_p.asp?idCategory= 3

Maybe there is a simple code I can add to the viewCategories.asp file. Please help if you can.
Thanks!!!!
