this my first post
what you need
2 buttons
6 wire repeaters
2 barriers
place two barriers like this
then place two buttons below the bottom barrier and one above the top barrier
wire both buttons to barrier to deactivate after the button is pressed
add 3 wire repeaters on each side of the barriers and make the delay to 10 for all wire repeaters and wire them together look this.
wire the button to the wire repeater then wire that to activate the barrier
wire the middle repeater to deactivate the door depending on if its below or above
lastly you need to wire the last repeater to activate the door that the second deactivates and it should look like this
