Unknown syntax error

Question

In my code, it’s showing that it has a syntax error, however everything remains functional. This began happening after this code was added:
<form action="http://www.youtube.com/" method="get">
<button class="button2" onclick=>Ad-Free YouTube</button>
</form>
I’ll link the code that is doing this in case of the issue being something else. It’s on line 89 for HTML.
