Javascript error getLogin()

Hi, there is a JS error caused by calling a function that is apparently not available. Can you please fix this.

Error:
“ReferenceError: getLogin is not defined”

Called in:

var quizSiteUrl = 'https://my_example.com';
										window.fbAsyncInit = function() {
					FB.init({
						appId    : '...',
						xfbml    : true,
						version  : 'v2.9'
					});
					FB.getLoginStatus(function( response ) {
						getLogin( response );
					});
				};
				(function(d, s, id) {
					var js, fjs = d.getElementsByTagName(s)[0];
					if (d.getElementById(id)) {return;}
					js = d.createElement(s); js.id = id;
					js.src = "//connect.facebook.net/en_US/sdk.js";
					fjs.parentNode.insertBefore(js, fjs);
				}(document, 'script', 'facebook-jssdk'));
