[Plugin: MF Gig Calendar] Calendar Not Showing

I installed the plugin and told it where to put the calendar (entered the URL on the settings page) but it doesn’t show up when I go to that page. Is there something else I need to do?

UPDATE: Okay, I figured it out and now it’s working fine. It might be helpful if you presented the instructions in two steps on the settings page, telling folks to add the URL but reminding them that they have to add that bit of code to the page itself. Those two important pieces aren’t presented at the same time, so it’s confusing. Other than that, I’m finding this to be exactly the plugin I need so far. Thank you!
