Dynamic Content to a MC

On the main timeline I have

_root.float.page_body = ‘’;
loadVariables(“content/flash/color_studies.txt”, _root.float.page_body);

and I’m using it to pass a txt file to a dynamic text field ( page_body ) inside a MC ( float ).

When the text field was on the main timeline, this approach worked great, but now all that appears in the text field is:

_level0.float.page_body

Any ideas where I went wrong?

Thanks
