How to move a rectangle (group of objects) up and down?

In the first trigger, the "else" statement will never execute. You should modify your top two triggers as follows:

Hello Nedim,

Thank you very much: it works!!!

To be honest, I don't understand why your version works and mine doesn't. The structure/logic of the triggers must be different then I thought. I have programmed a lot in the past, so I should understand it. I'm going to read the documentation to understand what's the difference between my reasoning and the reasoning of AS.

Many thanks!!

I will use the code provided by Nedim, but I just don't understand why my code (see attachment/image) doesn't work. What's wrong about it?

(the start value of 'going_to_the_top' is true)

@Alex: your solution is also very nice! Very understandable! Thanks!

Hello Nedim,

Thank you very much for your explanation! It's very clear! Your are right: my mistake was indeed that I should have used a toggle instead only setting the variable 'reached_top' to true. The interface of Articulate Storyline is a bit strange, but I slowly get used to it!
