Connect FB Pixel using code

Hi everyone, I installed a FB pixel in this WooCommerce website: https://scarpettadivenere.it/
Pixel Helper says that an event code is detected but the pixel has not activated for this event. In fact, I’m not able to see purchases in my campaigns after one month of activity.

The code is:

Facebook Pixel Code –> <script>!function(f,b,e,v,n,t,s)
{if(f.fbq)return;n=f.fbq=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};
if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version=’2.0′;
n.queue=[];t=b.createElement(e);t.async=!0;
t.src=v;s=b.getElementsByTagName(e)[0];
s.parentNode.insertBefore(t,s)}(window, document,’script’,
‘https://connect.facebook.net/en_US/fbevents.js&#8217;);
fbq(‘init’, ‘PIXELID’);
fbq(‘track’, ‘PageView’);

fbq(‘track’, ‘Purchase’, {value: <?php echo $order->get_order_total(); ?>,
currency: ‘EUR’});</script> <noscript><img height=”1″ width=”1″ style=”display:none”
src=”https://www.facebook.com/tr?id=PIXELID&ev=PageView&noscript=1&#8243;
/></noscript> <!– End Facebook Pixel Code –>

How can I fix it? I’m interested in Views and Purchase events only.

Thank you very much for your support!
