    resolved [RESOLVED] JQuery Callback Function

    I'm having an issue with jQuery UI not firing my callback function when it's not nested. This is my code which works (view on http://www.toolwebshop.com/_calorie_tracker/website/)

    HTML Code:
    <script type="text/javascript">
    	/* <![CDATA[ */		
    		$(document).ready(function() {
    			$("#slider").slider({
    				value: <?php if($_POST['lose']) { echo $_POST['lose']; } else { echo "0"; }; ?>,
    				min: -15,
    				max: 15,
    				step: .25,
    				slide: 
    				function calculate(event, ui){
    					profile		= new Object();
    					profile.n 	= $("#name").val();
    					profile.w	= $("#weight").val();
    					profile.h	= $("#height").val();
    					profile.a	= $("#age").val();
    					profile.s	= $("#sex").val();
    					profile.m	= $("#activity").val();
    					
    					$("#lose").val(ui.value);
    				
    					if( profile.s == "M" )	{ profile.bmr = (66 + (6.23 * (profile.w - ui.value)) + (12.7 * profile.h) - (6.8 * profile.a)) * profile.m; }
    					if( profile.s == "F" )	{ profile.bmr = (655 + (4.35 * (profile.w - ui.value)) + (4.7 * profile.h) - (4.7 * profile.a)) * profile.m; }
    					if( profile.s == "P" )	{ profile.bmr = (1155 + (4.35 * (profile.w - ui.value)) + (4.7 * profile.h) - (4.7 * profile.a)) * profile.m; }
    					
    					$("#bmr").val(Math.round(profile.bmr));
    					
    					$(".calper").each(function(){
    						calper = parseInt($(this).children(".percent").text())/100;
    						$(this).children(".number").text(Math.round(profile.bmr * calper));
    					});
    					
    					if( ui.value < -10 && $(".warning:hidden")){ 
    						$(".warning").fadeIn("slow"); 
    					}
    					if( ui.value > -10 && $(".warning:visible")){ 
    						$(".warning").fadeOut("slow"); 
    					}
    					if( ui.value == 0 )	{ $(".lose label").text("Maintain Weight:"); }
    					if( ui.value < 0 )	{ $(".lose label").text("Lose LBS:"); }
    					if( ui.value > 0 )	{ $(".lose label").text("Gain LBS:"); }
    				}
    			});
    		});
    	/* ]]> */
    	</script>
    However, i'd like to call that calculate function outside of the slider, without having duplicates. Here's what I would think should work, but isnt:

    HTML Code:
    function calculate(event, ui){
    				profile		= new Object();
    				profile.n 	= $("#name").val();
    				profile.w	= $("#weight").val();
    				profile.h	= $("#height").val();
    				profile.a	= $("#age").val();
    				profile.s	= $("#sex").val();
    				profile.m	= $("#activity").val();
    				
    				$("#lose").val(ui.value);
    			
    				if( profile.s == "M" )	{ profile.bmr = (66 + (6.23 * (profile.w - ui.value)) + (12.7 * profile.h) - (6.8 * profile.a)) * profile.m; }
    				if( profile.s == "F" )	{ profile.bmr = (655 + (4.35 * (profile.w - ui.value)) + (4.7 * profile.h) - (4.7 * profile.a)) * profile.m; }
    				if( profile.s == "P" )	{ profile.bmr = (1155 + (4.35 * (profile.w - ui.value)) + (4.7 * profile.h) - (4.7 * profile.a)) * profile.m; }
    				
    				$("#bmr").val(Math.round(profile.bmr));
    				
    				$(".calper").each(function(){
    					calper = parseInt($(this).children(".percent").text())/100;
    					$(this).children(".number").text(Math.round(profile.bmr * calper));
    				});
    				
    				if( ui.value < -10 && $(".warning:hidden")){ 
    					$(".warning").fadeIn("slow"); 
    				}
    				if( ui.value > -10 && $(".warning:visible")){ 
    					$(".warning").fadeOut("slow"); 
    				}
    				if( ui.value == 0 )	{ $(".lose label").text("Maintain Weight:"); }
    				if( ui.value < 0 )	{ $(".lose label").text("Lose LBS:"); }
    				if( ui.value > 0 )	{ $(".lose label").text("Gain LBS:"); }
    			}
    				
    			$("#slider").slider({
    				value: <?php if($_POST['lose']) { echo $_POST['lose']; } else { echo "0"; }; ?>,
    				min: -15,
    				max: 15,
    				step: .25,
    				slide: calculate(event, ui)
    			});
    What am i doing wrong? All i did was remove the function from within the slider().

    Bleh

    Still haven't had any luck with this. jQuery UI has some flaws in it though, that's for sure.

    Figured it out

    Found the answer on my own, aparently jquery UI doesn't let you call functions directly, you have to define a function and then call the function you want within that. Code as follows:
    Code:
    $("#slider").slider({
    	value: 10,
    	min: -15,
    	max: 15,
    	step: .25,
    	slide: function(){ calculate(event, ui) }
    });
