I know this has been answered a million times in a million ways, but I can't seem to understand what I am doing wrong.  I've looked at a lot of posts, and have gotten errors ranging from string is in improper format to having noting show up on the page.

Basically, for my church I have a worship schedule page, with subpages for each worship service.  Worship Service Documents have a dateAndTime.  I want to list future Worship Services
