I think that what you mean is something like this:
$ConnecctionAttempts{'JOBID'} = { ++$other_hash{'attempts'} };
That takes the value of the key 'attempts' from the other hash (you did mention
another hash, no?), increments it by one, and assigns the new value to the key
'JOBID' in the $ConnectionAttempts hash. Notice the ++ operator in _front_ of
the variable; this makes sure that the value is incremented _before_ returning
the new value and assigning it to the hash.
