Getting links from a XML file

1

A while ago i downloaded this file from the kirupa forum. I wanted the button on the project image to be a link but cant get it to work. Can someone help me out. Even one of the textfileds can be a link as well, so i can write the url in the xml file and it loads something like www.kirupa.com in the textfiled and when clicking it the link works. Please help me out. Thanks
