I'm making a custom map, and there are custom spawn points, but when I tried to use this: /spawnpoint @p -80 61 804

Nothing happened, and I respawned at worldspawn with the text:

"Your home bed was missing or obstructed"

I tried it in chat, in a command block, I tried switching the prefix (@p - @a - @e[type=player]) but nothing seemed to work.

Pls fix
