How do I make different spawn / home for each player?

Hi everyone :)

Here is the goal of my mod:

- By clicking on a specific block,  the player open a GUI which allows him to set this coordinates to 1 among 5 places available. 

And here is my procedure:

Once the place 1 is defined, the player can right click a specific item which also open a GUI to choose where he wants to go. 

And once he clicks on the Place 1 button which has been defined, he should be teleported at the world and coordinates defined thanks to the block... but not :( Here is my procedure:

Once I clicked to set the global variable (on block), I have this  message: [main/INFO] [STDERR]: [net.mcreator.simelya_retour.MCreatorSetPlace1:executeProcedure:17 Failed to load dependency entity for procedure MCreatorSetPlace1!

Have you some ID? Also I can give you my global variables, it can be useful:

I hope you could help me, thanks you !
