Hi Peter,
I had problems following your link, because there seems to be an unwanted space between “shire” and “folk”. I think the correct link is:
I tried filling in the contact form, and it took me to http://shirefolk.org.uk/shirefolkcontact-go1.php, which was blank (as you say).
There are some instructions here on how to use the Send Form Action. Are there any steps that you might have missed?
Getting forms to work reliably is also an increasingly difficult task, because of anti-spam measures, as @waltd has noted.
