>> Line 2 and 7 - You already defined "diffy" as an array in line 2, you can not declare it again.

Use the following script:

<script type="text/javascript">
var numberArray = [696,039,231,909025,5325,326,983] ;
var differenceArray = new Array();
for (var s = 0; s < numberArray.length; s++)
{
differenceArray[s] = numberArray[s + 1] - numberArray[s];
}
document.write("The original numbers:<br /><br />");
for (var d = 0; d < numberArray.length; d++) 
{
if (d != numberArray.length - 1) {
document.write(numberArray[d] + ', ');
} else {
document.write(numberArray[d]);
}
}
document.write("<br /><br />The differences between the numbers:<br /><br />");
for (var a = 0; a < differenceArray.length; a++) 
{
if (a != differenceArray.length - 1) {
document.write("Difference between " + numberArray[a] + " and " + numberArray[a + 1] + " is " + differenceArray[a] + "<br />");
}
}
</script>
