You don't want to use the gauge option with a counter-type variable
(ifInErrors and ifOutErrors are counters.)

What is probably happening is that you are not getting enough data for mrtg
to pick up.  Assuming you're running mrtg at the default 5-minute interval,
you need to have at least 300 errors.  (300 errors / 300 seconds)  Any less
than that will be seen as 0.

Look at the 'perminute' and 'perhour' options.

Don't forget to change your YLegend tag as well.
