Flash Linear Background

Hello,
i have a problem with flash linear background. I made part of the BG linear, and i changed the HTML in publish settings to ‘percentage 100 and 100’ etc, what it said in the tutorial on this site, so i when i published it i opened the swf file and it worked, but when i uploaded both the html page and the swf file to my site and tried it, it did not work! What can be the problem? I have a newer IE, version 6 i think, soi dont think that is the problem. thanks
