Answer
Before making changes, print out what you have in case you make a mistake

Required values on the TN

CLS: HTA (and FBD - Do not use FBA)

HUNT: nnnn - The DN where calls should ring upon busy

HUNT: 000 - If calls should ONLY hunt to the next line/key, and nowhere else.

Your DN must be MARP on your TN

LHK: n - The key number of the last DN key that should be included in a "Hunt up to the next key" scenario
