You misspelled the name. daivd != david

This is wrong. The MNAME should be mail.rm-cpa.com. and not rm-cpa.com.

You missed most of the records. You only have one NS record for the
zone instead of the two listed in the TLD. You need to add www2.mrbrklyn.com
as an NS record to your zone file. You have a whole bunch of RFC 1918
addresses in your zone file. Private addresses should not be visible in a
public zone. All of those station* and student* addresses should be removed.
My asterisk here represents a number. Also one of your MX records fax
points to superman which is also a 192.168.0.* IP Address.
