Trap Processor Message Config

Hi,

I have a device which sends a SNMP trap message to the OpManager. The corresponding MIB is uploaded. If my custom made trap processor processed the message with $* the following result is displayed:

sysContact.0: Martin , sysName.0: Processing Unit , sysLocation.0: Office , unit2MsgIndex.1: 1 , unit2MsgText.1: Door Lock 1 , unit2MsgStatus.1: locked

The bold value is initially sent as a integer value (12) an interpreted by the MIB as "locked".
My intention is to readout only the bold interpreted value, I tried with $5 instead of $*.
But in this case the integer value "12" is displayed.

Any ideas, why in one case the integer value is interpreted and in the other not?

best regards
