The error message returned from the Registry is:
540 : Attribute value not unique
Please help me!
540 Attribute value is not uniqueA supplied attribute value is not unique. This occurs when the registrar is adding a domain name that already exists in the registry, a server that already exists in the registry, or an IP address that is already being used by another server in the registry. Another possibility occurs when performing domain modifications and the registrar is adding a server that is already in the list of servers for the domain name or setting a domain name to a status to which it is already set. The RRP STATUS command MAY be used to determine current domain name status before attempting to change the status. When modifying or adding a name server, the IP address of the name server might not be unique. The registry MUST not allow IP addresses to be used by more than one server.
Were you trying to do any of what was stated above?
