.Swf will not load

I am working with flash builder and I load a swf in by grabbing a URLRequest and using the loader to load it.

My problem is that when I export my .swf as a release build to upload it to a site, The swf is just blank, I assume because the external swf is not part of my main .swf or something along the lines of that.

Is there away to get it to work?

I need to find out as the gamejam deadline is in a couple of days

Thanks
