I know this topic is everywhere but I cant find a solution to my particular problem.  I have been using a download center script for about a year. http://download.redgalaxy.net/ However, the title is static, keeping with the predefined one.  I am trying to get the title to change so it matches the file name shown on the display page "index.php/?nav=display&file=25". I have spent days trying to figure something out with absolutely no luck. Does anyone have an idea how to get the title to change when dynamically? Out of desperation i used an onload javascript but it doesnt work with crawlers. Thank you in advanced.
