ZScript items not appearing

[Wiw]

I'm having trouble getting my ZScript working. It worked fine when I set it up before, but here I get errors in Doom Builder which say:

DECORATE warning in "DECORATE:0". File is empty.
SNDINFO warning in "gzdoom.pk3\sndinfo.txt", line 260. Include file "SNDINFO" is empty.

The thing is, neither of those files are in my new set-up. I mean I used DECORATE before, but I switched it over to ZScript. I'm not sure where I messed it up, but it appears to be stopping my ZScript items from appearing in the editor as well. So what do I do?

Do not use Doom Builder, use Ultimate Doom Builder.

For your ZScript item (actor) not appearing in the editor, see this post

Make sure that your map does not contain a lump called DECORATE.
Check it with Slade3.

Yes, perhaps I should've mentioned that I do use Ultimate Doom Builder, it was just shorthand. Anyway, thanks for reminding me of the MAPINFO thing, I completely forgot I had to do that before.
