Entering in data (User Name & Password)
<p>Here is the problem:
For example if I enter in "A" as the user name and "A" as the password, then click add user nothing happens. But if I go back in and now type "B" for the user name and "B" for that password and click add user it adds the previous entry "A" &amp; "A" into the table. Like it's one behind?</p>

<p>I know I have something out of place.</p>
