I've set the date format to dd/mm/yy but when you submit it's not showing any events even though there are events in the database:
http://www.tmsa.org.uk/music-events-scotland.asp (you'll notice on initial load of this page that there are events in November in the Forthcoming Events and Homecoming Sessions sections.
EDIT: Sorry, I hadn't changed the form references on the results page. Will just try that, but I'm sure that's the issue. Appreciate the help.
