82186 UPS/FED-EX Shipping Calculator

I have about 5 projects I am going to be placing here within a month or two. Some big, some small. I don't have the time to do them all and could use some help. Here is the first one. (Small) I have setup a shopping cart at the following address: [login to view URL] Right now when it checks out... it calculates shipping, but it is not very accurate. I would like three things: 1. I would like it to calculate shipping by pulling from UPS or Fed Ex variables so that it is accurate. (weight, size, and distance shipped etc) 2. Everything on the backend (admin area) of this website "was" working fine, but somehow now when I want to add or edit an item it's giving an error. Some little bug in my database and I don't have the time to look right now. I need this fixed too. (All the products in the database are going to be deleted so we can start fresh). 3. I would like a link on the admin page that allows the user to grab the .mdb file and save the most recent version to their harddrive. Thanks for your bids. Director
