Help with adcin and serout, using a 16F688 Chip

:confused: Need some help with using analog inputs and sending results out serial to a LCD. I am expecting to see Low_Val= 0 to 254 on a LCD screen, What I am see on the LCD is Low_Val= 1 or Low_Val= 0. It is the same on all serial out on the LCD.
Using a 16F688 chip
Programing using PBP V3

Code I wrote so far is this: :confused:

you need to read the chapter on adcin, the input channel is not a pin number or pin alias its the analogue channel desired

Richard Thank You I am feeling really stupid right now. Again Thank you for you reply. :p
