Помогите доработать Slider jQuery UI

$(function() { 
    $("#slr").slider({ 
        range: "max", 
        min: 1800000, 
        max: 30000000, 
        values: [1800000,30000000], 
        stop: function(event, ui) { 
            $("#lbl").val($("#slr").slider("values", 0)); 
        }, 
        slide: function(event, ui) { 
            $("#lbl").val($("#slr").slider("values", 1)); 
        } 
}); 
$("#lbl").change(function() { 
    var value1 = $("#lbl").val(); 
});
