Looking for a JavaScript I can use for a Marquee that scrolls up with text that needs to be timed to coinside with an audio mp3 that is about five minutes long. Found other scripts that uses scroll speed 1, but the scroll does not match up with the audio after about two minutes of running. Need to have the scroll speed set to the length of the audio. I need a script I can copy and paste into a webpage, as I am not a JavaScript programmer. Any help will be greatly appreciated. Thank you
