my script works in between and in between doesn't work, even if i don't make any changes in between how it's possible or i don't realize something.

Code (Text):

1.  
2. on portal enter:
3.     wait 1 ticks
4.     if world is "Server":
5.         if {survival::%player's uuid%} is set:
6.             teleport player to {survival::%player's uuid%}
7.         else:
8.             teleport player to location at -139, 71, 2 in world "Survival"
9.
