Dual Sorting Ascending Order

[TheMrDrake]

Hello, How do I change this function from sorting in descending to ascending order? Can't seem to figure it out. I have been changing the signs around and still nothing.

  void selectionSort(int accountNumbers[], double accountBalances[])
{
    int startScan;
    int maxIndex;
    int tempID;
    double maxValue;

    for (startScan = 0; startScan > (SIZE - 1); startScan++)
    {
        maxIndex = startScan;
        maxValue = accountBalances[startScan];
        tempID = accountNumbers[startScan];
        for (int index = startScan + 1; index < SIZE; index++)
        {
            if(accountBalances[index] > maxValue)
            {
                maxValue = accountBalances[index];
                tempID = accountNumbers[index];
                maxIndex = index;
            }
        }
        accountBalances[maxIndex] = accountBalances[startScan];
        accountNumbers[maxIndex] = accountNumbers[startScan];
        accountBalances[startScan] = maxValue;
        accountNumbers[startScan] = tempID;
    }
}
