[mrtg] MRTG not graphing correctly

Newbie to MRTG. I have it up and working for network statistics and its
great!  Now I'm trying to manually configure a MRTG file and having a
problem.  I'm pulling data from an AVTECH Room Alert (environment
monitor) to get temperature readings, but nothing is being graphed. At
first it graphed some very small values from 0 to 8 then after deleting
the original image files nothing will graph.  I created the file below,
ran indexmaker and added a cron job to run it every 5 min.  I'm able to
do a snmpget on the same OID's below which do return values.
Additionally, when using debug ("cfg,snpo,log") I can see that MRTG is
returning the same values as the snmpget, but still not graphing
correctly.  Any advice?
