Question : DNS entry not returning CNAME record.

I have a domain I would like to use for my .Mac account. I manage my own DNS running BIND 9.2.4. I have created the record below. Also below is a DIG and NSlookup. I can dig the domain, but nslookup says, "can't find".  Can someone please show me what I am doing wrong? Thanks in advance.

Answer : DNS entry not returning CNAME record.

Here is a modified snapshot of what a DNS record looks like on our server:

$TTL 86400
@       IN      SOA     n1.domain.com. postmaster.domain.com. (
                                        2007110801 ;Serial
                                        10800   ; Refresh every hour
                                        3600    ; Retry every hour
                                        604800  ; Expire after a week
                                        86400 ) ; Minimum ttl of 1 day
        IN      NS              n1.domain.com.
        IN      NS              n2.domain.com.
