Uncaught TypeError: Cannot read property 'top' of undefined

jQuery(document).ready(function($){
     
var $el = $('.bloc-localisation');  //record the elem so you don't crawl the DOM everytime  
// stop here if no bloc-localisation element exists on the current page

var bottom = $el.offset().top + $el.outerHeight(true); // passing "true" will also include the top and bottom margin
console.log('bottom bloc gauche : '+bottom);
