Uncaught Cannot add undefined

[timdt]

Uncaught Cannot add undefined into the timeline; it is not a tween, timeline, function, or string.

 

Hey guys, sooo  first time i am getting this. Cannot understand why.

My other documents work but with this i am suddenly getting this weird error.

Must be something i am overlooking.

 

Btw everything is in one file because i am making something for google adwords

 

Help would be very much appreciated.

 

Side question: 

 

item 1 from x-250 to 0 (center) fade out(opacity 0 )

item 2 from x-250 to 0 (center) fade out(opacity 0 )

item 3 from x-250 to 0 (center) fade out(opacity 0 )

 

Could this be achieved with stagger? and how?

thankss!

Hello @timdtand welcome to the GreenSock forum!

 

This is happening due to not returning your timeline in your timelineone function. GSAP add() method expects a timeline being returned when you have a function.

 

So your missing this inside timelineone() fucntion

 

return tl;

 

And all together

 

function timelineone(){
	var tl = new TimelineMax();
	tl.from(".tekst1",1,{x:250})
  	  .to(".tekst1",1,{scale:0.1,autoAlpha:0});
  
 	return tl; // your missing this line
}

 

And now you can see your animation run

Nice work, Jonathan. Thanks!

timdt from your side question it looks like you might need 1 staggerFrom() for the x and another simultaneous staggerTo() for the opacity.  Maybe something like this:
