cannot set ftp username and password

[anakkk]

Hi, my hosting is using plesk 7.0.3, i tried to setup ftp authentication for my website, after click ok, it prompts me a message saying that "some fields are empty or contain an improper value. Do not use quotes, space and national alphabet characters in a password. The password should be between 5 and 14 characters and should not contain the login name as its part."

Had I missed out something?
