hi
first, just incase,
<? echo "this is text"; ?> works without ( )
and if you are posting form data to the current page
you can do :
<form name="whatever" method="post">
else, if posting to another page,
<form name="whatever" method="post" action="page.php">
and about dreamweaver, maybe you should try to reinstall it.
I use it just fine with php
