Program Not Running End Of File

Can some 1 help please? im trying to get a computer to control 2 mining turtles, however the "go" function works and they will go mining how ever when i change the input of the redstone to false (which should stop then and make them return to their original position) they only stop and dont go back to their original postion, help :P/>/>

There's one 'end' too much.

Where? the end on the miner is needed.

At the end of file. unless im badly mistaken, that's the one. BTW, get yourself a notepad++ or something like this, it can collapse LUA functions for better view.
