Character falling through moving elevator - SOLVED

This has been asked before, but the threads Ive read didnt seem to get a satisfactory resolution…

So I post my version… now with added video!

So I made this game to day with my kid on my knee (all his ideas and he designed the cardboard robot) but I ran into a problem…

Why does he fall through the magical egg-cup? Robotti is using the standard controller, with Rigid body attached, and the eggcup has a mesh collider (also tried a simple box collider) and also a rigid body…
There are some numerous settings for rigid body, but what is correct?
Please help?

hallo, I use this, found somewhere here, on a trigger inside the lift

var platform : Transform;
var player : Transform;

function OnTriggerEnter () {
   player.parent = platform;
}

and this on a trigger just when exit the lift

var platform : Transform;
var player : Transform;
 

function OnTriggerEnter () {
  player.transform.parent = null;
 
}

using OnTrigerExit on the trigger is in the lift don’t know why, but don’t work
