LoadMovie Troubleshoot help!

Hi there all,

I am fairly new to the Flash side of web development…

I have just started to make a site out of flash, and am using the loadMovie variable/constant. I have made an intro to my site, and it has an enter button on there, and the actions for the enter button are
on (release) {
_root.contents.loadMovie(“mainsite.swf”);
}

but when i load the .swf file up, and click the button, the old content doesnt go away, and results in having the intro and the mainsite there ??

check it out for yourself

kind regards
