Making Buttons Work

Please Help: Following is the code from one of my pages. There are 3 buttons: 1. Add To My Collection 2. Export Selected 3. Print Selected. The export and the print both work correctly. When I click "add to my collection" I get "page not found" error. I must be missing a line that connects the button to moving the selected items to the correct location. But, I anything but a programmer and I do not have a clue what it could be. Thanks, Janice
