Hi!

I’m not new to AS2 but to AS3 I’m a complete rookie.

Attached are two versions of a menu that I developed. The AS2 Version is working great, but the AS3 is a disaster. If you test the movie you’ll get this Output:

_TypeError: Error #1010: A term is undefined and has no properties._  
_at AS3Menu\_fla::MainTimeline/AS3Menu\_fla::frame1()_

Please help me understanding what am I doing wrong.😑

Change the for loop to:

for (var i:Number = 0; i\<=aItemsMenu.length -1; i++)

it’s trying to access a part of the array that doesn’t exist.

Thanks 🙂 it worked 🙂

Now how do I make this part work.

> function mouseEventClick(event:MouseEvent):void {  
> trace(“Click Working”);  
> this.gotoAndStop(2);  
> }

…this was so simple in AS2:| …

That will work, it’s just that you don’t have a frame 2 on your timeline. 🙂

this.gotoAndStop(2);

“this” in your code is a relative reference to the main timeline.  
you have to reference the instance name of the child mc.

Ah yeah, if you are trying to go to frame 2 of the menu items Cloptic is correct. I assumed you were trying to navigate around the root timeline.
