I'm clueless about your OID output as text, but I will tell you that 
this target line will not work. MRTG must have 2 instances on a target 
line, and there is no way around it. What you can do is this:

Target[]: at a.b.c.d
Options[]: /already existing options/, NOI

This tells MRTG to poll the same OID for both In and Out, but on the 
options line its saying to ignore the In and so only the Out will chart.

Try the new target and see if this error goes away.
