    // Once within the loop, we can create fetch information from the post's custom fields
    // Some of this is contingent on whether our event is All Day or Multi-Day,
    // so we first need to declare variables for these values. In PHP, if you
    // want to pass a value between conditions (if / then statements), they need
    // to be declared outside of those conditions first. So even though we 
    // don't know yet if an event is All Day or Multi-Day, we just have to
    // establish a starting point. Let's assume that the default is that
    // events are neither All Day or Multi-Day.
    $allday = false;
    $multiday = false;
    
    // The reality as to whether these variables are true or not is
    // stored is stored in the checkboxes, which I happened to call
    // 'scheduling options'. So let's get that first:
    $scheduling_options = get_post_meta( get_the_ID(), 'scheduling_options', true);
    
    // All events have a start day, so let's get that
    $start_date = get_post_meta( get_the_ID(), 'advwp_start_date', true );
    
    // The full picture of what is the beginning and end of an event
    // isn't just the day - it's the time. To be able to sort and organize events
    // by start time, especially when they are in the same day, we need to
    // have a value that is both the day of the event and the time of the event.
    // We don't know that just yet, but let's create those variables and set
    // their default value as just the day of the event - which we already have in
    // $start_date.
    $start = $start_date;
    $end = $start_date;
    
    // Now, based on the value of our $scheduling_options, we will figure out
    // whether custom fields exist for start and end time, and set those. This
    // begins with the condition that there are NO scheduling_options, meaning
    // neither of the boxes were checked - or the default state of the event.
    
    // The !$scheduling_options means "No value for $scheduling_options".
    if ( !$scheduling_options ) {

      // $start and $end variables to include day and time
      $start = $start_date . $start_time;
