[Plugin: Participants Database] ShortCode problem

***Newbie disclosure***

I am a complete Newbie. Naive but trying to learn. Don’t yell at me for asking stupid questions, please.

I can’t get the shortcode to work on my page. Can someone help give me, in newbie laymans terms, some direction here? Here is the page on the test site:

Thanks in advance for all of your guidance. I’ll make you proud, eventually.
