MTclip and javascript

I have a main page on my site and i am loading the main info into an empty movie clip. now i am adding a page in the empty clip which has new window code in it. for some reason the new window wont open.? i tried putting the javascript on the main page and on the page inside the empty clip but that didnt seem to do the trick. also i have turned off popup blockers and everything cause i know someone will tell me to do that. any help would be much appreciated. thanks
