Removing more then one item from an array after clicking twice using socket.io

app.js
queueing = [];

//Add to queue socket.on('add queue', function(data) { queueing.push(data); console.log(queueing); delete data; //Remove From queue socket.on('remove queue', function(data) { console.log(queueing.indexOf(data)); queueing.splice(queueing.indexOf(data), 1); console.log(queueing); delete data; });

index.ejs

$queueStart.click(function(){
            <% if (user) { %>
            var $id = <%=user.id%>;
            console.log($id);
            <% } %>
            socket.emit('add queue', $id);
            delete $id;
        });
        $queueStop.click(function(){
            <% if (user) { %>
            var $id = <%=user.id%>;
            console.log($id);
            <% } %>
            socket.emit('remove queue', $id);
            delete $id;
        });

after trying to add to the queue twice with the same user it sets the index of the id to -1 (tested with only two users)

any idea why thats hapenning and how to fix it?
