try using the Button Book Me pressed trigger instead of the currant page submit trigger.
if yu are still having problems, compress the consult.php page into a zip archive and send a copy of that page so I can see the code for the entire page.
I would have made button trigger but I did not have that option....I only get "any form post", "before page loads, "current page submit" and "no rules defined". (I'm in OSX 10.6.2, DW CS4) So what would be my next course of action ? Per your instructions the consult.php page is attached
