            $( "#addtrade_want" ).append($(object));

            }
        }

function submit() {

    console.log("Submit called!");

    var comment = document.getElementById("comment").value;

    if(items_left.length > 0 && items_right.length > 0){

            var data_post = {comment: comment, h_1: items_left.shift(), h_2: items_left.shift(), h_3: items_left.shift(), h_4: items_left.shift(), w_1: items_right.shift(), w_2: items_right.shift(), w_3: items_right.shift(), w_4: items_right.shift()};

            console.log(data_post);

            $.ajax({
                type: "POST",
                url: "trade_insert.php",
                data: data_post,
                success: function(){
                    alert("Trade sent!");
                    window.location.replace("mytrades.php");
                },
                error: function(){
                    alert("ERROR!");    
                }

            });

    } else {
        alert("You must add at least 1 item to each side!");    
    }
