Fix the following UCLID5 code using the compiler feedback provided below.

```

module main {
    // Variables definition
    var coin : integer;
    var dispensed_drinks : integer;

    // Initialization
    init {
        coin = 0;
        dispensed_drinks = 0;
    }

    // Transition relation
    next(coin) :=
        case
            coin < 10 : coin + 1; // Maximum coins allowed is 10
            true : coin;
        esac;

    next(dispensed_drinks) :=
        case
            coin > dispensed_drinks : dispensed_drinks + 1; // Dispense drink only if there are enough coins
            true : dispensed_drinks;
        esac;

    // Safety property
    // Ensure the number of inserted coins is always at least the number of dispensed drinks
    invariant safety_property {
        coin >= dispensed_drinks
    }
}
