Reference to this question: Scale each instance by index

I kinda made it work with the answer provided in the previous post, but I'm having a hard time figuring out how to loop the instances when it reaches the end of the sequence.

What am I missing here:

Here is how you can do a looping animation in geometry nodes:

enter image description here

I use the frame, compare this to the index, and scale only that instance on this frame. On the next frame, the next "index"/instance will be scaled. And so on. To get the looping effect i need indizes from 0..10. So i use module with number of instances to get his effect.

result:

If you want to change the speed of the animation, just plug in a map node in between like this:

by changing the "to max" values you can change the animation speed.
