Which is fine, but if you're expecting "growright", you won't get it on 
this graph. You don't have "bits" and that's good, it won't do you well 
here. Certainly not the cause of your problem but just wanted to let you 

When you run MRTG do you get any error message or does it just run as if 
nothing went wrong?

Your maxbytes is only 100, is that enough?

In your previous message you said you ran an SNMWALK and got what you 
wanted, but in reality you need to run an SNMPGET on that OID to verify 
its working for you. a WALK will get an instance below yet it will look 
like the OID you walked worked. Hard to verbalize but trust me, you will 
  easily eliminate a potential glitch quickly by using a GET instead of 

Other than that, I have no suggestions.
