The delegation of the zone points to dns.navarrocollege.edu and 
dns2.navarrocollege.edu.  The zone itself contains NS records pointing 
to columbia.johnwyoung.org and gemini2.johnwyoung.org.  Since these 
names are in the zone they host, they need to have glue records in the 
parent zone.  But they don't, because they aren't in the delegation from 
the parent zone.

Fix your zone to match the delegation (or vice versa) and you should 
have better luck.
