PC Binary Teleporter Hub problems

[raular5]

Hi,
I decided to build a teleporter hub from wich I would teleport to diferent places of my world using binary switches.
The problem comes when I test a prototipe and from 0-7 position seems to work but not further :/
Here are some pics:

The idea is to use the 4 switches to choose a teleporter and the other switch to actually teleport.

I would like to know if you can find the mistake that leads to the prototipe not working properly.

*Btw this is my first post in this forum so if u find anything i did wrong please tell me .

With teleporters, only teleporter that was found first and last, will be activated. You're choosing the first one correctly by activating it from the logic gate, but last one changes after midpoint to teleporter labeled zero, so you're not getting teleported. You need to run an extra wire length between start and 15 to make sure your origin is last to be found. Which might not be too practical if you intend to spread these teleporters around the world.
