Using ccs compiler and in circuit emulator I have run the program below on my PIC16f877 without success!

What I want to achieve is to output the lower 8bit result(contained in adresl register) of the A2D conversion onto port B where 8 leds are connected.  Does anyone know what I am doing wrong?

> #include<16F877.h>
> #use delay(clock=20000000)
> #byte port_b = 6
  #byte adresl = 9E
  #use fast_io(b)
>
> void main (void)
> {
>    long value;
        int lowvalue;
>
>    setup_adc_ports(RA0_ANALOG_RA3_REF);
>    setup_adc( ADC_CLOCK_INTERNAL );
>    set_adc_channel( 0 );
>       set_tris_b(0);
>    do {
>          value = Read_ADC();
>          delay_ms(100);
>          lowvalue = adresl
>          port_b = lowvalue;
>    } while (TRUE);

Yup, should work.
