I Need Your Help in making a button invisible/visible

Childsplay, I know. But I'm new to Macromedia Flash 8 and I just can't solve it. :( I've been googling around and have yet to find an aswer. Please help.
myButton is my Button's instance name

This is my code in the button I want to make invisible
on (release){
trace("The code went here 2");
_root.myButton._visible = false;
trace("The code went here 3");

stop();
}

I can also put the code in the frame's actionscript if that's all it takes:
stop();
trace("This code went here 1");

Man, first of all. Draw your button. Convert the button in Clip, after open the actions. Add this code:

Code:

---

on (press)
{
        this._visible = false;
       
        // change "bla bla bla" to text of you want
        trace("Bla Bla Bla");
}

---

test and see if this is what you want. PS.: I think stop() is only to put in main frames o.O
