JS one of my functions does not seem to exist

Question

I have a function :

var postBet = function(enemyID, ip_1, ip_2, playerID) {
    $.post("save.php", {
            enemyID: enemyID,
            ip_1: ip_1,
            ip_2: ip_2,
            playerID: playerID
        },
        function(data, status) {
            document.getElementById("saveWarningText").innerHTML = data;
            $("#saveWarningText").fadeIn(100);
            setTimeout(function() {
                $("#saveWarningText").fadeOut(100);
            }, 3000);
        }
    );
};

Unlike all of my other functions when I attempt to call it I get: Uncaught ReferenceError: postBet is not defined

Full code:

        printResult(

Turns out 000webhost was using a cached version of the website. It was using an older version of my code without that function. Fixed the problem by deleting and re-uploading my code to 000webhost.
