._alpha properties to Dynamic text fields

hello everyone.
Im sure this is somting simple (or at least I hope it is), but how can I get my dynamic text fields to be respond to alpha properties?

The movie I am working on has a movie clip which includes 4 dynamic textfields. I want the entire clip to start at 0 alpha and when certian conditions are met the entire thing will fade up. I have it all working except for that even when the rest of the clip is at 0 alpha the dynamic textfields remain visible.

Whats a girl to do?

Thanks!
