Heyas,

I kind of tried combining two different codes to create a branch mining code that will branch mine, as well as return the items to the start, but for some reason it's not working. When I run it, it just comes up with the shell again (after initiating mining sequence), instead of actually initiating the mining sequence. If someone could go through the code and possibly tell me what's wrong/botched about it?

Added: Fuel not needed as I'm running an older version of ComputerCraft.
