Hi,

So this is the problem?

You need to add an "exit;" to tell PHP to terminate the if-loop.
If oyu don't do so the rest of the script is executed and thus
the empty usrname and password are entered. That's why you
get "usrname already taken" after the second submit.

here again. but if your username is unique entering it to the DB won't
work anyway and you could leave it, but I think it is cleaner to put
it there.
You could also put the whole processing into a seperate script and then use
header(...)s to redirect back to the loginscreen.
hope it helps
