Dynamic text not updating

Question

This seems like a simple problem, but I can't find any explanations as to why this is happening.

I want a menu with buttons, that when you rollover a button, text at the bottom of the menu shows a little explanation of the button. In each of my buttons I have something like this:

on (rollOver) {_global.tool="Speed"; trace(_global.tool);}
on (rollOut) {_global.tool=""; trace(_global.tool);}

I traced to see that the variable really is being updated when it's supposed to, and it is. Problem is, the text at the bottom of the frame isn't. It's dynamic text with the variable set as "_global.tool" At the beginning of the flash I set _global.tool="none"; and it shows up as "none" even when _global.tool has changed. If I leave the menu and come back, then it has updated, but I need it to update while I'm on the menu.

Hope I explained well and that someone can help. Thanks in advance.

I believe you cannot assign a compound variable name to a textfield. I recommend you don't use the variable aspect of the textfield at all--they are fidgety and I avoid them. Just assign an instance name to the textfield and assign the text to its text property...

on (rollOver) { toolTextField.text="Speed"; }
on (rollOut) { toolTextField.text=""; }
