Completely by chance, I was able to solve this one on my own.
I rewrote line 3 (the 2nd map) as: map { [ $_, $_->get_value('ipHostNumber') ] } and it worked. If there is a cleaner way however - please let me know. Otherwise, hopefully someone else can be helped by this post. - Patrick Cable, Patrick wrote:
