'ERROR: Macro AND?BCL not found in macro file.' What does that mean??

Hello I wonder if anyone has seen this error.

After sorting through a few wayward endif's this is the only remaining error that pbpw displays. I'm attempting to compile for a PIC 16F628A.

The code attached is designed to drive a small rover bot using 3 infra red detectors along a black line (hey! a line following robot, how original!) I haven't had the chance to test the code (since it won't compile) although sections have been used in different programs on the same robot.

Don't worry, I figured it out.

I was trying to do a bitwise boolean operation as an expression in an If...Then.
Now I've discovered it's the very least of my problems.
