Proteus + ADC simulation

[Megahertz]

Hi, it is the first time I am trying to run a simulation of my ADC code in proteus, but I am facing a problem - I cannot even blink an LED currently. Following is my code to blink an led:

Include "modedefs.bas"
DEFINE OSC 4       ' OSCCON defaults to 4MHz on reset
DEFINE OSCCAL_1K 1

@ __Config _INTRC_OSC_NOCLKOUT & _WDT_ON & _PWRTE_ON & _MCLRE_OFF & _BODEN & _CP & _CPD

pause 50
VALUE VAR WORD
PORTA=0
PORTC=0
TRISA = %001000
TRISC = %001000
CMCON = 7
ANSEL=%10000000
ADCON0=%1011100
ADCON1=%01010000
ANSEL = 0
OPTION_REG = %10001111

SWITCH_ON VAR ADCON0.0
START VAR ADCON0.1
CHECK VAR PIR1.6

START1:

WHILE 1
TOGGLE PORTC.5
PAUSE 100
WEND
GOTO START1

I have also attached a screenshot of my proteus connections. Once I get this corrected, I will run a simulation of battery monitor using ADC. Thanks
