wrong javascript code?

What is wrong? i want to create a new html side with this code, but it show only a white side:

<script>
&lt;script src="//code.jquery.com/jquery-1.10.2.min.js"&gt;&lt;/script&gt;
&lt;script src="//dta8vnpq1ae34.cloudfront.net/javascripts/jquery-ui-1.10.4.custom.min.js"&gt;&lt;/script&gt;
&lt;script src="//dta8vnpq1ae34.cloudfront.net/javascripts/pitchprint.min.js"&gt;&lt;/script&gt;

var designer;

$(document).ready(function () {
	initializeEditor();
});

function initializeEditor() {
	designer = new W2P.designer({
		//set the customize now button to disabled untill the designer is ready...
		$("customize_now_button").attr('disabled', 'disabled');
		apiKey: "0611d2263c6396d78ee016446d91cee6",
		globalUrlPrefix: "https://pitchprint.net/app/",
		designId: "2835067ec048692279e9d09de1327153",
		autoInitialize: true,
		product: {id:'PID_12', title:'Sample Business Card'},
		mode: "new",
		onReady: on_ready_function,
		onSave: on_saved_function
	});
}


function on_ready_function() {
	$("#customize_now_button").removeAttr('disabled');
	$("#customize_now_button").click(function() {
		designer.show();
	});
}

function on_saved_function(_fromDesigner) {
	designer.unload();
	console.log(_fromDesigner);
}

</script>
