Rob,
  The "MOV W,PWM_Count" is not needed. The very next instruction "MOV FSR,#PWM_Value" will clobber W anyway.
  The code will work ** IF ** PWM_Count happens to be in the global RAM area (that is it's address is <$10).
  If PWM_Count is NOT in the global RAM area, when FSR is changed PWM_Count will not be accessable.
