Solved Cooldown help

Hi I'm fairly new to skript, I coded this to give my players items but I don't want them to be able to spam it, what should I add if I want to make them wait 30 seconds between right clicks?

on right click on villager holding a cauldron:
    if difference between {rewardcd.%uuid of player%} and now is less than 30 seconds:
        send "&cYou must wait %difference between 30 seconds and difference between {rewardcd.%uuid of player%} and now% before doing that again." to player
        stop
    set {rewardcd.%uuid of player%} to now
    set {_chance} to a random integer between 1 and 200
    if {_chance} is between 1 and 24:
        make console execute command "/msg %player% &2Treat! &7>> &2Take some Golden Candy"
