A few things. I'm a novice with the slider (started using it yesterday), the jQuery UI Google Group might be a better place to post this, and I think you should post an example on a test page somewhere.
That said, try this and see if it works. $(document).ready(function(){ $("#mySlider").slider( { min: 1, max: 720, steps: 720, slide: function(e, ui){ if(ui.value > 0){ $("#sliderVal").text(ui.value); } else{ $("#sliderVal").text("0"); } } }); });
