Loading text dynamically into MC: MX

Hey guys,
I would like to load text dynamically form my server into my flash movie.
That I know how to do. I have 2 frames on 1 layer.
Frame 1=

loadVariablesNum("content.txt", 0);

Frame 2=

stop

(text box) set to dynamic txt, multiline…

But when I try the same thing within a movie clip, I have trouble getting the text to display. The text box pops up but no text from my content.txt file.
Any help would be great.
thanks
