Solved right click holding a skull

[Hartvig]

I want to make a profile gui, but i get a error, i've tried "on rightclick holding a skull of player"

Code:

on join:
    set slot 0 of player's inventory to skull of player named "&a%player%'s Profil"
    
on rightclick holding a skull:
    open chest with 3 rows named "&aDin Profil" to player

Error:
