Solved Set location to a variable.

[Kezard]

on join:
set {spawn.%player%} to location at (0.5, 66, -1.5) in world "sb%player%"

I'm guessing there is an error because the world has %player% in it but I don't know how to fix this.

Try this:

on join:
    set {_loc} to location at (0.5, 66, -1.5) in world "sb%player%" parsed as world

Thank you for the help!
