External text source html formatting

A movieclip with a textbox in it is loading text from a php script using:
Movie_mc.loadVariables(“script.php”, this, “GET”);

The text the php script echos back has basic, supported HTML tags in it. Flash will either show the text with the tags as if it were normal text, or it will not show the text at all.

Using:
“text_txt.html = true;” and “text_txt.htmltext” does not work.

Selecting ‘Render text as HTML’ for the textbox makes no text appear at all.

When the font is not embedded, the text does not display.
When the font is embedded, the text shows up with the tags visible.

Does anyone know another method that should work?
