So, ${if1input} is expanded to "Counter32:" and so is ${if1output}.

By changing your script so that it outputs numbers in stead of
"Counter32:".  What do you think?

Change the line "/usr/local/rrdtool/bin/" and so on into the following:

echo "debug: >>${if1input}<<  >>${if1output}<<"

As long as your script does not return the following
(the numbers will be different of course)

   debug: >>12345<<  >>23456<<

then don't even think about rrdtool yet.  For help on shell programming,
seek a mailing list/usenet group on shell programming.
