Question about nested distribution lists

[Moragtao]

Thank you for this, however it's still giving me the same problem I was having before. If I try to use this to add just a contact to the distlist, it works like a charm. However, if I use this to try to add a previous distlist to the new distlist, it still doesn't work. It'll create the new distlist, but won't add the previous one to it.

EDIT: I tried it with a different contact group name, and it sort of worked. It added the name of the contact group, but nothing else.
