Alarm, Cavebot label to go back to dp if someone attacks me

[exsar]

I was trying to make that, but for my surprise it always has to start at that point, because if i get pked near the exit and i start the emergency label on the deepest point of the cave its really useless, i have to say its a cave with different levels of floors, so someone can explain me how to make a label to go depot if someone attacks me correctly? im stucked right here
