Issue with Dreamweaver CS3 Check username behavior

Question

Let me start by saying that I'm not a developer, and I may be in over  my head on the project I'm working on.
I'm creating a  page to register new user's information into aa Access user table. I've  created a registration form, and added the Insert Record behavior. That  works fine, no problems. However, when I add the Check New User  behavior, I get some strange results.
If the new  username is valid (not a duplicate), the form processes and goes to my  "thank you for registering" page. Great.
If the new  username is not valid, the behavior redirects to the "sorry, pick a  different username" page. Great.
When the user goes  back to the registration page to change the User Name and tries to  submit the form, and error message appears thet the connection  (MM_rsKey) is still open. When I look at the code (with my very limited  knowledge of actual code), it looks like the behavior doesn't close the  connection unless the selected User Name is valid. If the redirect  happens, and the user goes back to the registration form page, the  connection hasn't been closed, and the form simply won't process.
I've  even tried splitting the registration into 2 parts... I created a form  with only the User Name field and a submit button, thinking I'll just  make the second part of the process an update, where the additional  information is added to the existing record that matches the user name,  but still no joy.
I even checked to see if the code  that closes the connection resides on the redirect page, but I don't  think that's the case.
I'm probably missing some  perfectly simple step, but I just can't seem to figure it out.
I  appreciate any help with this. Thanks in advance.

Yes, that's really how that behavior is meant to be used. You could even take it a step further and have a password field on the first page.
The only issue I have with that scenario is is for some reason, the user doesn't complete step two - then you essentially have the account created but not complete. So then you have to add some sort of check upon login and direct the user back to step 2 if he never filled out that part.
So you may want to start thinking about eventually building a registration page where it's all containined on the same page. The prococess would be something like this:
1. User enters all required information,  including username and password.
2. The page is submitted, but before the insert record occurs the check new username runs, or some variation of it.
3. If it passes, the record is inserted and rediects to the confirmation page.
4. If it doesn't pass the check, instead of a redirect like the behavior does, it displays a message.
5. the tricky part here is not to lose all the other entered information. That can be retained in a session, and bound back to the input fields.
That's just an overview, and i'm sure you've seen enough web forms to recognize the workflow - usually with registration forms and online shopping and checkout forms.
