Dilan-

Way down at the bottom of your code shown...this may not be _the_
problem, but it can't be helping:

 ; ADC Control and Looping


  BANKSEL ADCON0  ; Bank 0
 loop BSF ADCON0, GO
 poll NOP
  BTFSC ADCON0, GO
  GOTO poll
  MOVF ADRESH, W ; Move result to W =20
  MOVF ADRESH, 1
  MOVWF CCPR1L  ; Adjust the PWM duty with Analog input
  BANKSEL PORTB  ; Bank 2
  MOVWF PORTB
  GOTO loop

  END

Looks to me like Bank 2 is the selected memory bank when the "GOTO
loop" instruction is executed.  However, the code following loop
assumes Bank 0 is selected.  Since the "BANKSEL ADCON0" precedes the
loop label, its generated code is only executed when "falling
through" into loop, rather than when branching directly to loop.

Hope that helps.
