Errors in accessing Table objects

Hi,

      I am trying to use the table objects. I am using the master agent-
subagent approach. My code runs as a subagent communicating with master
agent via default AgentX socket. The table object are external to the
subagent. I am using the table iterator approach for creating and accessing
the object. I am using the NET-SNMP-EXAMPLES-MIB and netSnmpIETFWGTable
which has been provided in the Net-snmp Wiki tutorials. But the issue is
whenever I try to do snmpset or snmpwalk I get the error messages. Can
anybody help me solve the issue.

SNMPSET
snmpset -v 3 -u myuser -l authNoPriv -a MD5 -A my_password localhost
nsIETFWGChair1.\"sming\" = "David Durham"
Error in packet.
Reason: wrongLength (The set value has an illegal length from what the agent
expects)
Failed object: NET-SNMP-EXAMPLES-MIB::nsIETFWGChair1."sming"

snmpset -v 3 -u myuser -l authNoPriv -a MD5 -A my_password localhost
nsIETFWGChair2.\"sming\" = "Karthik"
Error in packet.
Reason: wrongLength (The set value has an illegal length from what the agent
expects)
Failed object: NET-SNMP-EXAMPLES-MIB::nsIETFWGChair2."sming"

SNMPWALK
snmpwalk -v 3 -u myuser -l authNoPriv -a MD5 -A my_password localhost
netSnmpIETFWGTable
Error in packet.
Reason: (genError) A general failure occured
Failed object: NET-SNMP-EXAMPLES-MIB::netSnmpIETFWGTable

These are the debug info from the snmpd.log file
