Trap Viewer message parsing

Hi,

I'm trying to parse a trap viewer message and the variables dont appear to be working as intended.  I'm wondering if someone could help.

if i do ${MESSAGE} as a whole it comes back with:

SNMP Trap

     Received Time:2/5/2014 1:11:00 PM

Source:XXXXXXXXXXX

     Community:MPLS

     Variable Bindings

pwe3.2.1.2.1.38.1073993729:= 2

          pwe3.2.1.2.1.38.1073993729:= 2

fdryPwServiceType:= 3

snAgGblTrapMessage:= MPLS: VPLS HEcustomertest peer is down

snmpTrapOID:= FOUNDRY-SN-ROOT-MIB:pwe3.2.0.1 (1.3.6.1.4.1.1991.3.1.2.0.1)

          sysUpTime:= 228 days 21 hours 21 minutes 10.45 seconds (1977607045)

experimental.1057.1.0:= 10.0.126.4

snmpTrapEnterprise:= FOUNDRY-SN-ROOT-MIB:pwe3.2 (1.3.6.1.4.1.1991.3.1.2)

I'd like to parse out the messages as MPLS: VPLS HEcustomertest peer is down

I've tried ${snAgGblTrapMessage} and ${snAgGblTrapMessage:}

I've data is located in the trapvarbinds table in the OIDValue_Unicode field, but i can't get it to display...any ideas?
