Interval is starting twice after cleared
<p>I am trying to create an interval and send request. It will start with click and stop with click. Starting and stopping working great. But after stopping the interval when you pressed the button again to start it, interval starts twice. After stopping it and start it again, it starts 3 interval.</p>

<p>Here is my code:</p>

<pre><code>var running=0
var pathArray = window.location.pathname.split( '.html' );
var pathArray = pathArray.reverse();
var pathArray = pathArray .join('');
var pathArray= pathArray .split('/');
var bidnum=pathArray[3];
    $(document).ready(function(){

        $('body').append("&lt;div id=\"cdjs\" style=\"position: absolute; top: 30px; background-color: gray; box-shadow: 0px 0px 0px 3px; left: 30px;\"&gt;Click to start&lt;/div&gt;");
        $('#cdjs').click(letswin); 

    });

    function checkandbid(){
            if(running==1){
                $.get("http://www.bigibid.com/LiveResponder/LR.bid?_as="+bidnum, function(data){
                    Marray = data.split("'te':'")
                    time = Marray[1].split("'")
                    time = time[0]
                    $('#cdjs').html(time);
                    if(time &lt; 2 &amp;&amp; able==1){
                            able=0;
                            $('#ctl00_ContentPlaceHolder1_ibBid').click();
                    }else{
                        able=1;
                    }
                });
            }
    }

        function letswin(){
            if(running==1){
                    running=0
                    clearInterval(IntRun);
                    delete IntRun;
                    $('#cdjs').html('Click to start'); 
            }else if(running==0){
                running++
                delete IntRun;
                clearInterval(IntRun);
                var IntRun = setInterval(checkandbid, 300);
                }

        }

    function bidders(){
    }
</code></pre>
