I need for "admin edit product page" to have an html editor contrib installed. This is an oscommerce shopping cart. Here is the contribution: [login to view URL],1347/category,all/search,html+editor I only want it installed on the admin product page and the mailing list page. I DO NOT want the "DEFINE MAIN PAGE" installed. Also, please do not mess up / break the multiple image contrib already installed. Please view image for notes.
