amp-carousel

My amp-carousel is no longer working. Also, the script I validated says the cdn address is wrong.
<script async custom-element=”amp-carousel” src=”https://cdn.ampproject.org/v0/amp-carousel-0.1.js”></script&gt;

<amp-carousel width=”400″ height=”300″ layout=”responsive” type=”slides” autoplay delay=”7000″>
