Jups, going the right way.
some tips:

 - To execute a command, use backquotes. Like this: in=`snmpwalk foobar`

 - You'd better use snmpget instead of snmpwalk (because you want to poll
just one value)

 - Use the format options of snmpget to get just the value (and not the oid,
the type of output, etc)

greets,
