Loaded SWF Problem

I’ve got two flash files, main.FLA and page.FLA

my main.FLA loads page.SWF at runtime. I have code in page.FLA that accesses the stage property of a MovieClip called content that I have sitting in page.FLA. When I run page.SWF by itself I do not get any errors, but when I load that SWF into main.FLA at runtime, I get an error saying that I’m trying to access a null object reference.

Through testing I have concluded that this error is telling me that content.stage is null. Can anyone tell me why I can’t access the stage property of a MovieClip when I have loaded that SWF into another Flash file at runtime? It sure seems to me that if the code runs correctly in page.SWF, that I should be able to load page.SWF into my main flash file and still run the code with no problem.

Thanks.
