Solved Once a life time a win

[Djavan]

Hey everyone!
I am bussy with a script that give people things from opening crates.
I want that if someone won the /launch permission command, he can't get it anymore.
Can you guy's help me with this?
Thanks!

​

command /trollcrategui:
    trigger:
        set {_waited} to difference between {trollcrate.%player%.lastused} and now
        if {_waited} is less than 5 hours:
            message "&cJe moet %difference between 5 hours and {_waited}% wachten voor je dit weer kan proberen!"
            stop
     
        chance of 10%:
            send "&cJe hebt gewonnen"
            wait 5 ticks
            make server execute command "/launcher permission command"
            send "&cJe kan nu het command: /launcher gebruiken"
        else:
            send "&cJe hebt niks gewonnen"
     
        set {trollcrate.%player%.lastused} to now
