I have a dynamic textbox on the stage with an instance name of textBox. I’m trying to put the time varible in it and I have traced time and the values work correctly with my other classes. I get this error: 1120: Access of undefined property textBox. What am I doing wrong? Thanks for help!

```auto

public function addTime(value:Number) : void
{
            time += value;
            textBox.text = String(time);
}

```
