How to acces a dynamic text field inside a movieclip

[Newbie 123]

Hi Im still a beginner at this and im attempting this code and I was wondering how I would go about accesing a text field inside a movieclip? Any help would be appreciated, plz and thank you.

from the parent timeline of the movieclip, after the textfield exits:

this.mc.tf

where mc is the movieclip instance name and tf is the textfield instance name.
