zabbix & trap &trigger help

[alescri]

Good morning,
I have a problem with the zabbix configuration and snmp traps.
a device sends me this trap

SNMPv2-MIB :: snmpTrapOID.0 type = 6 value = OID: US-HIQ-TRAP-MIB :: hiQNmProcessInitCompleteTrap
FSC-RTP-MIB-EVENT-MGMT :: rtpEvtSequenceNumberIndex type = 66 value = Gauge32: 1096086

the value 1096086 changes every trap and is the identifier that will also be used to close the problem.
I don't understand how I can create a trigger, which refers to that value.
could someone help me?

thanks

i created this tag ID {{ITEM.VALUE}.regsub("FSC-RTP-MIB-EVENT-MGMT::rtpEvtCurrId\stype=66\svalue=Gauge32:\s(.*)\ s","\1")} this tag contain the ID of the allarm
is possible to create a trigger to compare this tag to another ?
like } ?
{{ITEM.VALUE}.regsub("FSC-RTP-MIB-EVENT-MGMT::rtpEvtCurrId\stype=66\svalue=Gauge32:\s(.*)\ s","\1")} = {FSC-RTP-MIB-ALARM-MGMT::rtpArmCiCorrIDs.0\stype=4 \svalue=STRING:\s(.*)\s","\1")})}?
