Hi,

I'm trying to use FormMaster2008 for the DNN registration on a website. I have setup a form with all sorts of fields: firstname, lastname, email, password, address, country, phone, etc. And I have created an extra table to store all those details. So when someone hits 'register' the details are saved in the DNN users table as well as in my custom table. However, when someone enters a username that already exists he gets the error "UserAlreadyRegistered", which is obvious. The problem is, the 'register' button disappears from the screen and the data is submitted to my custom table.

How can I make sure that whenever someone enters a username that already exists, they get a warning and the details are not saved in my database? I think I need to check for duplicate usernames in the database, but I can't figure out how to do this.

I hope someone can help.
Thanks,
Mark
