Hi there, I've been trying to do a little Oblivion modding and I'm running into a problem with adding new dialogue to the game. The problem being, I can't seem to get it to work.

I started off trying to add a simple topic and response to a custom NPC. After trying and failing many times to get that to work, I tried to do the same to a vanilla NPC to see if the problem somehow laid in the NPC I had made. But the result is the same: the topic I added does not show up in the list in-game. Here are screenshots of both the quest and topics windows- the content of the these is functionally the same in either case I have tried, except for the NPC meant to say the line.

I would greatly appreciate any insight into what I am doing wrong. If it's relevant, I am using the Construction Set Extender.
