Loop player not working

[FegeFege123]

I have a skript

every 1 tick:
	loop all players:
	if loop-players location is "29, 72, -17":
		if loop-players world is "parkour":
			broadcast "work"

but it gives me an error

There's no loop that matches 'loop-players location' (parkour.sk, line 153: if loop-players location is "29, 72, -17":')

can someone help me fix it?

at first: every 1 tick is very buggy, will cause lots of lag for your server.
second: Im not sure you want to use the broadcast expression here, more like message "work" to loop-player.
Because right now it will spam every single person in the server (not mattering which world) 1  × how many players are in that world per tick

You have to specify a world to check the location of, e.g. every 1 tick in world "world" or loop all players in world "world".
