how to add asyn src to

I actually just saw that async and src are in this <script src=”https://cdn.ampproject.org/v0.js&#8221; async></script>

but… does it need to be in the right order?

if so… how the hell do I edit the header for the amp page? I cannot find it for the life of me.

that is the page…. in google developer console… it does shoe amp validation passed…. but search console is saying I still am missing required attributes: src, async
