Where are da dynamic text fields?
Actually, if you can trace the dynamic text fields, the problem is probably layers (not levels). If you drag the layer with your dynamic text fields up, you will probably see them.
Why are you trying to do this in one swf? Also, if it were me, I would put all content on one frame and use _visible=true; to show contect per user event.
If I have not answered your question, post your .fla. I am sure that if I can see it I will be able to explain why the dynamic fields are not showing.
