Error building ASN.1 representation

hi all:
I am working on net-snmp agent, and I create a table with two
indexes, when I start the agent and get value from the table using
snmpv3 protocol, I get the following error:

netsnmp_assert pss->s_snmp_errno != (-11) failed snmp_api.c:3119
snmp_build()
send response: Error building ASN.1 representation (build objid: bad
first subidentifier)

-- SNMPv2-MIB::sysLocation.0
-- SNMPv2-MIB::sysORLastChange.0

the mib browser I use is MG-SOFT mib browser, when I use snmpv1, I
can get the integer value but if I use snmpv2 or snmpv3, I get nothing,
the browse display " Index discovery running...", and the agent give
the errors above.
I have no any idea about this, would anyone can help me, I paste
the code and the mib file below, Thanks a lot.
