This option displays the lines above! These are probably blank.
This is because this option ONLY displays a list of walks that have been cancelled.
I would recommend putting this code at the top of your hoe page. Then when a walk is cancelled the home page will automatically display a message and list of the cancelled walks and the reason they are cancelled.
Code used above
$feed=new RJsonwalksFeed($rafeedurl); // standard software to read json feed and decode file
$display= new RJsonwalksStdCancelledwalks(); // code to display the walks in a particular format
$feed->Display($display); // display walks information
