What is wrong with my skript

[DrKarma]

I got this skript from a friend recently and it isn't working
on first join:
{firstjoin::%player's uuid%} isn't set
execute console command "broadcast &bWelcome! &c%player%"
execute console command "give %player% Wooden_Pickaxe 1 {Unbreakable:1}"
set {firstjoin::%player's uuid%} to true

let me check that script out and im gonna fix it for you : )
[doublepost=1580040238,1580039297][/doublepost]First of all you dont need set first join when you already wrote it in code "On first join:"
second of all you can't make "unbreakable" pickaxe without addons so i gave pickaxe unbreaking 1000

on first join:
    broadcast "&7[&6BROADCAST&7] &bWelcome! &c%player%"
    give 1 wooden pickaxe of unbreaking 1000 to player
    stop

#This made me make it easier to test script. YOU CAN REMOVE CODE BELOW TO  #
command /firstjoin:
    permission: first.join
    trigger:
        broadcast "&7[&6BROADCAST&7] &bWelcome! &c%player%"
        give 1 wooden pickaxe of unbreaking 1000 to player
#This made me make it easier to test script. YOU CAN REMOVE CODE UPWARS TO #
