Javascript not visible on live site

On my website I’m trying to set up some automatically created affiliate blocks. I want to show 3 products next to each other in 3 distinct colums. When I’m logged in, I can see it show up.

However, when I’m not logged in as the admin, nothing shows up. It should show up at the bottom after the sentence “Houd je nagels kort, deze zijn namelijk vaak de oorzaak van blaren tussen de tenen.”

I inserted the <script type=”text/javascript”>…</script> between <div class=”wp-block-column”>…</div> in the code editor.

Can anyone see why it is not showing up on my live site?
