Glitch with server validation
Not sure what's up here - basically its the validation that checks whether or not a username or email address is already being used.
I have three registration forms, and its working fine on two, but not on one.
I've been through it a few times now, and can't see where the issue is - as far as I can tell I have everything in the right place, so hopefully its just something simple I've missed.
Have attached the file below.
