SNMP mutiple indexes with 1 dynamic index

[rgruyters]

I was wondering if it is possible to use multiple index when searching for 1 dynamic index.

For example:

CHECKPOINT-MIB::fwAcceptPcktsIn.1.0
CHECKPOINT-MIB::fwAcceptPcktsIn.2.0

I have tried the following statement in Zabbix, but it doesn't work:
CHECKPOINT-MIB::fwAcceptPcktsIn[index,ifName,eth-s1p1].0

The last index (.0) gets removed from execution.
40085:20101125:152026.406 Item [foo:snmp.fwAcceptPcktsIn.1] error: OID [CHECKPOINT-MIB::fwAcceptPcktsIn.1] value has unknown type [0x80]

Hope someone can help me.
