Categories needed 'model'; 'qty'; 'category'; 'description_short'; 'vendor'; 'new_price'; 'description_ext'; 'weight'; 'backorder'; 'server_image_location';

    (headings specified will be changed just showing how many i need to pull from database)

5. find '$server_image_location'; and add to download list then download to our server 6. add '$supplier'; '$server'; to each array 7. if there is an entry in the database already it should keep the existing information & update as necessary for example if there is no description then it should update it, price changes it should record the previous price and then update the price to the new one eg $price becomes $old_price and $new_price becomes $price, if there is no $server_image_location apply no_image.jpg ---------------------------------------------------------------------------------------------------------------------- * Thanks for your time, any help would be appreciated Michael Seton xtpickles@gmail.com*
