I've been stuck with this problem for awhile and it's driven me mad.

There is one zone in my small map that I can't enter. The zone has two doors leading into it. However, neither of the doors work. When I walk up to one of them, the text that tells you to buy the door for a certain cost simply doesn't appear, and pressing F doesn't work at all.

1. I've checked that the zones are properly named, and the adjacent zones in the map GSC file are correct as well. I've also made sure that the zone volumes are info_volumes, touching each other, and have target, targetname, and script_noteworthy KVPs, so I don't think it's the zone volumes causing the problem.

2. The triggers for both doors are both trigger_use, and have the right target, script_flag, and targetname (zombie_ debris), and all the other options are default. The trigger is stretched so it extends past both sides of the debris models and clip (so you can open it up from either side, which is how I think it works). I don't think I messed this up, but I get the feeling that this is the part causing me problems.

3. The clip is a script brushmodel with the targetname and script_noteworthy KVPs, extended to cover the models.

4. Finally, the small rocks (which are the models acting as the debris that I want to move) are script_models with the targetname and target KVPs.

5. I have indeed added the script_structs with the approriate targetname.

I simply have no idea how the door just stopped working entirely, as I have been essentially copying my doors over, and I've been checking this over and again to make sure I got the KVPs right.

Any help would be massively appreciated!

EDIT: Simply deleting both doors and remaking the door carefully while watching a tutorial fixed it. I'm not sure what went wrong, but probably some stupid typo.
