Squid & MRTG possible?

Hi!

I upgraded my Squid to 2.0 PATCH 2 to be able to use the SNMP interface.
The upgrade was succesfull but I can't poll the SNMP variables from MRTG!
Here are a sample error from MRTG:

-----

SNMP Error:
  Received SNMP response with error code
    error status: noSuchName
    index 3 (OID: 1.3.6.1.2.1.1.3.0)
  SNMPv1_Session (remote host: "proxy.euronet.be" [195.74.193.21].161
                    community: "public"
                   request ID: 1828825305
                  PDU bufsize: 8000 bytes
                      timeout: 2s
                      retries: 5
                      backoff: 1)
SNMPGET: Failed to reach target:
"1.3.6.1.4.1.3495.1.3.2.2.1.2.5&1.3.6.1.4.1.3495.1.3.2.2.1.2.5:public@proxy.euro
net.be". I tried multiple times!

Any idea? I would like to use the following OIDs:

'cacheHttpAllSvcTimeFiveMin' => '1.3.6.1.4.1.3495.1.3.2.2.1.2.5',
'cacheHttpMissSvcTimeFiveMin' => '1.3.6.1.4.1.3495.1.3.2.2.1.3.5',
'cacheHttpNmSvcTimeFiveMin' => '1.3.6.1.4.1.3495.1.3.2.2.1.4.5',
'cacheHttpHitSvcTimeFiveMin' => '1.3.6.1.4.1.3495.1.3.2.2.1.5.5',
'cacheIcpQuerySvcTimeFiveMin' => '1.3.6.1.4.1.3495.1.3.2.2.1.6.5',
'cacheIcpReplySvcTimeFiveMin' => '1.3.6.1.4.1.3495.1.3.2.2.1.7.5',
'cacheDnsSvcTimeFiveMin' => '1.3.6.1.4.1.3495.1.3.2.2.1.8.5'

Regards,
