here is the ccs code:

#include <18f4550.h>
#use delay(clock = 20000000)
void main() {
unsigned int16 value;// Input variable
setup_adc_ports(ALL_ANALOG);// Input combination
setup_adc(adc_clock_internal);// ADC clock
set_adc_channel(0);// Select RA0
setup_ccp1(ccp_pwm); // Select timer and mode
setup_timer_2(T2_DIV_BY_16,248,1); // Clock rate & output period
while(1) {
value=read_adc();//Get input byte
set_pwm1_duty(value);// Set on time

everything is exactly same as previous post + a simple potentiometer which is connected to pin2.

here is the execution:
