giving a speech, / conversion tab how do I set up?

I wish to create an NPC that goes to a certain location and gives a multi-line speech the player can listen to, if desired, then goes about sandboxNPC stuff.

What works
going to that certain location
Sandbox behavior
Dialogue with Player, is able to trade stuff in return for the player giving up certain items

What does not work:
My NPC says the first line of the speech set up in the conversation tab but does not move on to the following lines to complete it.

What I have done
I copied closely confessorcromwell, the children of atom preacher, since that NPC does what I wish my character to do. I copied as well the script he uses and made references to My NPC in the appropriate script file for Megaton as well where ConfessorCromwell is listed (this latter part may not be needed and ultimately, I do not want MyNPC linked to the stock megaton script).

In the script attached to ConfessorCromwell, when the player reaches 2000 within cromwell and cromwell is near the bomb reference, he gives his sermon.

If i duplicate exactly settings in the conversation tab for his speech, to include the "tick" conditions and scripting, My NPC travels to location correctly but says nothing.

If I check "random" and nothing else but have the "link to" boxes with the speech added in it, at least My NPC says the first line.

making a speech does not seem that difficult to do, is there some trick, some settings I need to look at in the conversation tab of the quest, or maybe I can just put MyNPC speech in an AI package (how to add in the scripts sections there if this is needed)

Thanks
