Dynamic text problem

I’ve got 2 movie clips, each one with a dynamic text field inside, sliding in from the side of the stage. Im using Myriad as the font and embedding all the appropriate characters. The dynamic text loads in some text from an array randomly.

When I run the movie, the text fields do not display. If I don’t embed any of the characters, then the movie works fine.

I’m confused; surely it should be the other way around??
