I have no idea why it doesn't work but that's prob cuz I never do stuff with tp but You can also do it like this

Code (Text):

1. execute console command "/tp %player% 2741 62 -746"

 

Oooooh sry now that I see it I didn't read it correctly

 

Try check location of event-block, not of player.

Code (Text):

1. on step on oak planks:
2.     send "test1" to player
3.     if event-block is block at location 2912, 61, -275 in world "world":
4.         send "test2" to player
5.         teleport player to location at 2741, 62, -746 in world "world"

 

Or claim a 1 block space with worldguard and then check for region.
