Thank you.  That makes it much clearer.

  [Though copying the text would have been sufficient.
   You didn't actually need to attach a screen dump]

Anyway:

So a GETNEXT request returns a value for
    .1.3.6.1.4.1.311.1.4.1.1.5.1.2.0

We then told you to ask for this value using "snmpget"

But this command isn't asking for the OID .1.3.6.1.4.1.311.1.4.1.1.5.1.2.0
It's asking for the OID 1.3.6.1.4.1.311.1.4.1.1.5.1.2
(without the final .0)

And the agent is quite correct.
There isn't a value associated with 1.3.6.1.4.1.311.1.4.1.1.5.1.2
There's a value associated with 1.3.6.1.4.1.311.1.4.1.1.5.1.2.0
but you didn't ask for that.

If you are using "snmpget", you must request the *EXACT*
same OID as returned by snmpwalk/snmpgetnext.
These two commands will do a "fuzzy match" to return the
next valid OID value.
   snmpget doesn't do this - it uses an *exact* match on the
specified OID.   If you give it an invalid OID, then it'll
complain.  (As here).
