SimpleButton help

I need to have a button that contains a text box, and have the text change. First, is there a way to access a text box directly in a SimpleButton? While I know this doesn’t work, it would look something like


btn.upState.textField.text="Text"

Second, since I could not get that to work, I made a movie clip, put the button i made in it, and simply put the text box over the button. The problem this creates is that when the mouse is hovering over just the button it is in the over state. When the button moves over the text box it goes back to the up state. Can someone explain why it does this and if it is possible for the button to still be in its over state when the mouse is over an object that is on top of the button itself?
Thanks in advance
