Can't add skies to maps

[lamb]

As the title says, I'm struggling to add a custom sky to a map I'm working on. I've looked at all the tutorials I can find and nothing helps. I'm probably just an idiot and skipped over something or screwed it up somehow but idk.


Here's the sky I'm trying to add (highlighted in yellow)


Placed in the designated box w/ correct spelling and all that jazz


And then the following pop-up



I've also tried adding PerpetualNight.sky but that won't work either.
Can anyone point out to me what I'm doing wrong? Any and all help would be appreciated! Thank you! :>

It's been a while since I've tried putting a custom sky into a map, but I believe you do not need to include ".sky" in the sky file box c:
