Markup Not Collapsing Despite Adding the code recommended in other forum Posts

Site URL: https://greenmountainssolar.com/

I have a markdown block which wasn't collapsing until I researched this forum and found a new code to use. Using the recommended code, the clock does collapse/expand once., but only immediately after I edit and save the respective page. It then reverts back to keeping the markdown in the expanded position. The code block is on each page, not the header. This is the code I copied in:

<script src="https://cdn.jsdelivr.net/npm/jquery@3.2.1/dist/jquery.min.js"></script>
<script>
     $(document).ready(function(){
    $('.markdown-block .sqs-block-content h3').css('cursor','pointer');
    $(".markdown-block .sqs-block-content h3").nextUntil("h3").slideToggle();
    $(".markdown-block .sqs-block-content h3").click(function() {$(this).nextUntil("h3").slideToggle();});
    });
</script>

Did you know there's a built in Accordion Block that doesn't require code?

Hi Paul, Yes I initially tried the accordian and found it less elegant. I find the accordian is very appropriate for short FAQs because closing the question you're on is simple. But for longer form information, the accordian will disorient the reader by going to the bottom of the text and forces them to scroll back up to close it.

That did the trick. Thanks Paul, you make the world work! Beer on me next time you're in Vt!
