Trouble adding commas to string

Question

I'm using a pretty standard function to add commas to a large
number (so that a number like 1000000 appears as 1,000,000). Below
is the actionscript I'm using.
When I define the variable debt as any number, the script
works perfectly. But if I define debt as a variable passed to the
movie from a PHP file, then the script puts the commas in the wrong
places (i.e., 10,000,00). Can anyone explain to me why this would
happen, and how to fix it?
var input = debt;
var inputString = input.toString();
var finalString = "$";
var count = 0;
var tempString = "";
for (var i = inputString.length-1; i>=0; i--) {
count++;
tempString += inputString.charAt(i);
if ((count%3 == 0) && (i - 1 >= 0)) {
tempString += ",";
for (var k = tempString.length; k>=0; k--) {
finalString += tempString.charAt(k);
return(finalString);

Answer 1

I can see that this is cleaner than my script. However, the
comma problem continues...

Nope, coming from PHP your var is already a string. Omit the
toString()
var input = "1000000";
//var inputString = input.toString();
var finalString = "$";
var count = 0;
var tempString = "";
for (var i = input.length-1; i>=0; i--) {
count++;
tempString += input.charAt(i);
if ((count%3 == 0) && (i - 1 >= 0)) {
tempString += ",";
for (var k = tempString.length; k>=0; k--) {
finalString += tempString.charAt(k);
trace(finalString);
