STM8S ADC Scan Mode not updating

[KDesr.1]

I am able to read my two ADC inputs individually when I implement the code shown in this example: http://embedded-lab.com/blog/starting-stm8-microcontrollers/13/

However, the ADC values in the buffers do not seem to be getting updated when I try to get the ADC to work in multi-input mode as per the example here: http://embedded-lab.com/blog/continuing-stm8-microcontroller-expedition/2/

I've looked at different locations in the ADC1_GetBufferValue() buffer, and none of them seem to be getting updated.

Perhaps I have modified something incorrectly for my application?

Here is my code, the specific device is the STM8S003F3.

#include "STM8S_DELAY.h"

#include "MY_UART.h"

{

char short_adc = 0x00;

char batt_adc = 0x00;

char tx_buffer[16];

int short_count = 0;

int i = 0;

  GPIO_Setup();

    ADC1_StartConversion();

    while(ADC1_GetFlagStatus(ADC1_FLAG_EOC) == FALSE);

    ADC1_ClearFlag(ADC1_FLAG_EOC); //clear the ADC conversion flag

  batt_adc = ADC1_GetBufferValue(2) >> 2; //update the ADC value

  short_adc = ADC1_GetBufferValue(3) >> 2;

  //Transmit the ADC value to the terminal

  my_itoa(batt_adc, tx_buffer); //convert the int to a string

  UART_SendStr("ADC value: ");

  UART_SendStr(tx_buffer);

  UART_SendChar(10); //LF

  UART_SendChar(13); //CR
