Screens toggle

I think I'doing something wrong. I want to to toggle these 3 screens. Everything works fine in simulator, but in a real LOGO it doesn't. Any explanation?

I would also like a solution to loop the screens, not to go uot of range over 3 or stop on 1.

Your program can also not work in the simulation.

Here a working version.

Thank you ixo. It seems LOGO has no secrets for you and you are willing to help. Much appreciated.

The loop is solved, thank to you, but I'm in the same dilema. The project works in simulator but If I load it in a real LOGO it doesn't work at all. Where is my mistake? It has to be one 

Unfortunately, I can't tell you.

I tested my suggestion in both the simulation and a real LOGO! 8.4.

Hi.

Another way to stop on screen 3. Not resetting back to 1 screen.

Tested on Logo 8.3
