add message to varible

on chat:
    if {amount.%player%} is set:
        add to {amountt::%player%::*}
        delete {amount.%player%}

on inventory click:
    if inventory name of player's current inventory is "&2&lKEYS":
        if clicked slot is 1:
            cancel event
            if 2499 *{amounttt.%player%} is less than {money.%player%}:
                remove 2499 *{amounttt.%player%} from {money.%player%}
                give player {amounttt.%player%} tripwire hook named "&a&lVIP Crate

its not really working, any ideas why?
