Calling a Function from a frame

programming flash
1

I have a simple problem. I’m trying to call a function from a frame in an animation.

The function


function goBack(evt:Event):void {
   gotoAndPlay(this.currentFrame - 100);
}

This code lives in frame 1 of my movie. On frame 143 I have this chunk of code.


goBack();

I get an error message saying…
[COLOR=Red]1136: Incorrect number of arguments. Expected 1.[/COLOR]

What is the reason for this? and how do I fix it?

Thanks.
