error- master file: out of zone ?

[R Owen]

First of all, thanks to those who corrected me on my mistakes regarding the protocol of this newsgroup, and my apologies for them.....

Now, my DNS won't return an authorititive answer, and I can't figure out why. It seems there is a problem with my zone file, some thing to do with being "out of range". Heres a couple of lines from my log file.......

dns_rdata_fromtext: teawamutu.net.db:3: near '7200': out of range
dns_zone_load: zone teawamutu.net/IN: loading master file teawamu.net.db: out of range

I've included my named.conf file, zone file, and the lines from my log file pertaining to named starting.
