Smoothing (example) won't upload to my Due (closed)

Hi,

This is my first post here, so please bare with me if i forget something, but i'll try to be as precise as possible.

I'm just trying to run the example "Smoothing" from the IDE 1.5.2 and upload it to my DUE board.

// Define the number of samples to keep track of.  The higher the number,
// the more the readings will be smoothed, but the slower the output will
// respond to the input.  Using a constant rather than a normal variable lets
// use this value to determine the size of the readings array.
const int numReadings = 10;

int readings[numReadings];      // the readings from the analog input
int index = 0;                  // the index of the current reading
int total = 0;                  // the running total
int average = 0;                // the average

int inputPin = A0;

void setup()
{
  // initialize serial communication with computer:
  Serial.begin(9600);                   
  // initialize all the readings to 0: 
  for (int thisReading = 0; thisReading < numReadings; thisReading++)
    readings[thisReading] = 0;          
}

void loop() {
  // subtract the last reading:
  total= total - readings[index];         
  // read from the sensor:  
  readings[index] = analogRead(inputPin); 
  // add the reading to the total:
  total= total + readings[index];       
  // advance to the next position in the array:  
  index = index + 1;                    

  // if we're at the end of the array...
  if (index >= numReadings)              
    // ...wrap around to the beginning: 
    index = 0;                           

  // calculate the average:
  average = total / numReadings;         
  // send it to the computer as ASCII digits
  Serial.println(average);   
  delay(1);        // delay in between reads for stability            
}

The following error appears when I verify the code:

'int index' redeclared as different kind of symbol:

A IDE V 1.5.2 (beta) software bug?

I work with an Arduino DUE R3
Software: Arduino IDE V 1.5.2 (beta)
OS X Version 10.8.2

Looks like the name 'index' is being used by the libraries. Pick a different name for that variable.

I feel like such a noob now.
John, Thank you very much!
