Andrew,

Sorry, I forgot to post everything I tried. I have put the quotes in
my command definition. This gives me the same result (when I also
remove the quotes from the service definition). If I leave the quotes
in the service definition AND the command definition, I get the same
output, but instead of an OK state I get a WARNING state.
