Looks like that NS doesn't answer for it:

Zone style:  Failure
1)  Your SOA records are wrong.  The first data field is for a name server, not the name of the zone.
2)  You don't need the $ORIGIN directive in your reverse zone - and it can introduce errors (if you misspell your zone).

The problem is that they repeated the "IN" on the NS line.  What was expected was an RR-type.
