Hi guidegirl, thanks for getting in touch and welcome to the forums!
Sorry for the trouble here. It looks like you may just need to try pasting that snippet into you functions.php file a little differently.
Are you able to try pasting it again right after the opening <?php tag at the top of the file? Does that change anything for you?
Otherwise, you can try pasting it at the very bottom of the file, but try wrapping in in PHP tags:
<?php // Adds HTML above Community Events form
add_action('tribe_events_community_form_before_template', 'my_custom_text'); function my_custom_text() { echo "
Here are some instructions for filling out this form:
"; echo "</pre>
<ol>
<li>Step 1</li>
<li>Step 2</li>
<li>Step 3</li>
<li>Step 4</li>
</ol>
<pre>"; }
?>
Let’s start there and see what we find. 🙂
Cheers!
Geoff
