hi followed the teacher and tried in different browsers , drawing pen does not work is something wrong with my code?

tried in chrome , then safari still wasn't able to run the drawing pen but the color swatch still works

var color = $(".selected").css("background-color"); var $canvas = $("canvas"); var context = $canvas[0].getContext("2d"); var lastEvent;

$(".controls").on ("click","li", function(){

$(this).siblings().removeClass("selected");

$(this).addClass("selected");

color = $(this).css("background-color");

});

$("#revealColorSelect").click(function(){ changeColor(); $("#colorSelect").toggle(); });

function changeColor () { var r = $("#red").val(); var g = $("#green").val(); var b = $("#blue").val();

$("#newColor").css("background-color","rgb(" + r + "," + g +", " + b + ")");

}

$("input[type=range]").change(changeColor);

$("#addNewColor").click(function(){

var $newColor = $("<li></li>"); $newColor.css("background-color", $("#newColor").css("background-color")); $(".controls ul").append($newColor); $newColor.click(); });

$canvas.mousedown(function(e){

lastEvent = e; }).mousemove(function(e){ context.beginPath(); context.moveto(lastEvent.offsetX,lastEvent.offsetY); context.lineTo(e.offsetX,e.offsetY); context.stroke();

});

You've wrote "moveto" when it should be "moveTo" (case-sensitive).
