The manhunt compass

[CPlock32]

So I am making a skript that tracks a player when the compass is right clicked, and I am having trouble with the conditional in the skript.

Code (Text):

1. command /track <player>:                                      
2.   description: Use this command to track a player by right clicking with a compass
3.   trigger:                                              
4.     set {target player} to  arg 1                              
5.     send "<yellow>You are tracking %{target player}%"              
6.     give compass to the player
7.  
8. on rightclick with a compass:
9.   if player and {targetplayer} is in world "world":                          
10.     set {track location} to location of {target player}                          
11.     set player's compass target to {track location}
12.     send "<light green>Compass is now pointing to %{target player}%"
13.   else if player is in world "world":
14.     send "<light red>%{target player}%<light red> is not in the Overworld"
15.   else:
16.     send "<light red>The compass does not work in this dimension"

When I test the skirpt on my server, the game says *player name* is not in the Overworld, so clearly the first conditional is not including all the scenarios I want it to. When the compass is used in the other dimensions, the correct text appears, therefore (if I'm correct) the problem is line 9:
"if player and {targetplayer} is in world "world"
(this line is meant to check if both the tracked player and the player with the compass are in the overworld)
Any suggestions on what to change?
