Thanks for the prompt reply.
I did not build the form with CSS form builder, just created it with Dreamweaver in the normal way. As it is an html page I cannot create a recordset on it.
The form posts to a file called regform.php which your programme Universal Email created. What I want to do (and I am sure most of your customers would want to do) is modify the code on this form so that it checks the database for a duplicate email address before dumping it to the database, and if it finds a duplicate does not do the dump and redirects to a page with a message.
