Text in textinput not being resized

Hi,

I have a flash client where in there are some text input on a movie, now my movie and text input are resized.
There is some default text in my textinput now when i go from the smallest size to biggest size (zoom in/out feature) the text in my textinput doesnt resize properly.
I tried applying font size according to the textinput size but didnt work.

Let me know of any possible solutions.
