Servo motor control with POT

Hi friends, I can not speak English well. Sorry. I'm doing a project. My goal; Using 2 potentiometers to control 2 servo motors separately. Now I can control 1 servo motor with 1 potentiometer. 2. I can not add potentiometer and servo motor. I'm coding and uploading the proteus file. Thank you very much for your help. I use Mplab XC8 and pic 16f877a.
