thanks guys!

define , initialize left offset variable outside of jquery actions:

var cssleft = $('#slider').css('left');  $('#slider').mouseenter(function () {     if ($('#slider').css('left') === cssleft) {         $(this).animate({             left: '0'         }, 300, function () {});     } else {         $(this).animate({             left: cssleft         }, 100, function () {});     }  });  $('#slider').mouseleave(function () {     $(this).delay(1000).animate({         left: cssleft     }, 500, function () {}); });

also, not put quotes around variable cssleft otherwise interpreted string.
