I have an error that has me stumped.
I have a form that inserts text from a text field into a
mysql database and I have added a check user name function to check
if this number already exists.
Here's the page
http://www.thechallenge.net.au/redemption2.php The error I get when using the page on the web is this
Duplicate entry '' for key 1
Can anyone help with this?
