set player head to variable

[claytyne]

hey i want to set a player head to a variable, but i can't figure out how. and is there a way to call an event when right clicking on a specific player head?

on rightclick:
    if clicked block is {_rare}:
        break clicked block
        send "&9You found a rare candy basket!" to player
        play sound "entity.bat.ambient" to player

(for the second thing)

You're not using {_rare} to set it are you? It wouldn't save to a local variable and be usable outside that block of code. I have a few custom items I've saved to variables and it works just by doing:
"Set {rare} to player's tool"
I do it in a command while holding it and set it.
