setInterval() not repeating. Works only 1 time

I'm trying to have a div's left property change by its self - one every second when your hovering over so I made this:

$(div.scroll_left).hover(function(){

    var left_num = $('div.license_video').css(left)

    var left_num1 = parseInt(left_num, 10) - 1;

    var timerID = setInterval(alert(left_num1), 1000);

    //var timerID = setInterval(slideleft(left_num1), 1000);

},function(){

    clearInterval(timerID);

});

//function slideleft(left_num){

    //$('.license_video').css('left', left_num + %);

//}

In theory you would think it repeat till you move your cursor off which clears the interval. When I hover over it does it one time and never repeats (there are no errors). Then when I hover off it gives a error Uncaught ReferenceError: timerID is not defined

setInterval isn't working at all. You aren't passing it a function as the first argument.

You are calling alert immediately and trying to use it's return value as the function to repeat.

var timerID = setInterval(function () { alert(left_num1) }, 1000);
