The meta key in your case has to be just club_name (the name of your custom field). The meta value needs to be {post_title} (since you want to compare the event’s custom field value to the title of the club).
At the end of the video I say that you have to select “Post ID” as the return type for the custom field instead of “Post Object”. This is not true. You can choose both. It does not have any relevance for the meta query.
