You shouldn't
need to do anything. The form replays the page after clicking submit and shows any validation errors.
However, it shows the errorlist on a version of the page that replaces the form,
instead of showing the form again with an error message above it, refilling in the fields that are okay and highlighting the error fields. Blech.
Someone said the core replacement Advanced Form pages are supposed to redisplay the form, like everyone is used to, but it doesn't seem to do that for me.
Also note that if the contact form is not the only segment on a page, all the other segments will be redisplayed again, regardless as to if there any errors.
One page I did has the message form at the bottom of several segments. I'm going to have to move it, because you can't see that there was a failure unless you scroll down to the bottom again

p.s. thanks, do I get a biscuit?
