UGHHHHHHHHHHHHHHHHHHHHHH

Can I make my turtle kill me?

I'm trying to make my turtle farm sugarcane, and it's not moving for some reason. It's supposed to dig so long as it detects a block in front of it, and then move into that space, and check again. It doesn't seem to want to move.

BLEEPIN PROGRAMMING.

Going back to listen to my Route1 program...at least Beep() likes me.

Btw, sugarcane farm looks like this, if any of you have suggestions:
X|XX|XX|XX|XX|X
X|XX|XX|XX|XX|X
X|XX|XX|XX|XX|X
X|XX|XX|XX|XX|X
X|XX|XX|XX|XX|X
X|XX|XX|XX|XX|X
X|XX|XX|XX|XX|X
X|XX|XX|XX|XX|X
O

Where X is sugarcane, | is water, and O is the turtle's starting position. It digs, moves forward, then starts the detect loop.
