As I've said with reviews on your other low level, low effort resources, any newbie Skripter could easily whip this up in a few minutes.
A few things wrong with this:
1) Your spawn command has no check to see if the variable was set. If it wasn't set, the command will just do nothing, and the player would be confused
2) The "stop" is 100% useless. Seeing this here shows me you don't have much at all for basic Skript skills
3) Your indentation for this command is using spaces, whereas the indentation for the setspawn command uses tabs. Again, this shows me that you probably copy/pasted this from another place and/or you really have no clue how to use Skript.
As Ive stated in other reviews, if you're going to post resources on SpigotMC, put some effort into them.
We don't need yet ANOTHER spawn command script, its been done to death.
Spend some time learning more Skript and post a resource when you've got something unique.
