I have been trying to install Facebook Pixel but not succeeding and I need help please.

When I add it to the template right above the </head> part where they say to add it (first screenshot), I get a syntax error when I try to save the template (second screenshot)
I don't know how to fix this and I have tried contacting FB but they are not responding, so I would appreciate it greatly if someone could lend assistance, thank you in advance!

I copy and paste the code directly form the facebook pixel install page...

This is it:
<!-- 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');
fbq('init', '1503549823290444');
fbq('track', 'PageView');
</__script>

<!-- End Facebook Pixel Code -->

You have to add {literal} {/literal} around the javascript code.

Or add in that code a space before and after the curly brackets.

Thank you, now I can save it indeed! Gonna try if it's working correctly now, thanks so much

The fact that the javascript code is visible means that there is an error somewhere else in your template. Make sure the code is being inserted right above the </head> tag as stated and that the tags are paired correctly.
Either of Rolf's suggestions work the same, so the error must be somewhere else.
