    Default 18f4550 ADC not responding

    I just wrote a simple program to check the operation of Analog to digital converter on my PIC18F4550, but the output is just meaningless. I have shown the program below, which is a simple program to control a stepper motor.

    I am not getting readings of (0 to 1023) on my lcd. Instead the value oscillates between ( 16 and 28 ) and most of the time unpredictable values.

    Plz help me out of this, I am stuck with this for 3 days...
