# Currency Cure

I have four input boxes that output a calculated total and the final total needs to be displayed as currency. I found the formatAsDollars function which looks like it does exaclty what I'm looking for. Now, how or where do I insert that "total" into the formatAsDollars function to get that result? My syntax savvy is not too good. I saw a lot of comments about the formatAsDollars function but no real clear answer as to how you run your dang variable through there! Not sure how to get it correctly within the Event handler as I've been notified many times. An example would be nice. Anyway, here's the code:

on (release, keyPress "<Enter>") {
message = total

function formatAsDollars (amount ):String {

// return a 0 dollar value if amount is not valid
// (you may optionally want to return an empty string)
if (isNaN(amount)) {
return "\$0.00";
}

// round the amount to the nearest 100th
amount = Math.round(amount*100)/100;

// convert the number to a string
var amount_str:String = String(amount);

// split the string by the decimal point, separating the
// whole dollar value from the cents. Dollars are in
// amount_array[0], cents in amount_array[1]
var amount_array = amount_str.split(".");

// if there are no cents, add them using "00"
if (amount_array[1] == undefined) {
amount_array[1] = "00";
}

// if the cents are too short, add necessary "0"
if (amount_array[1].length == 1) {
amount_array[1] += "0";
}

// add the dollars portion of the amount to an
// array in sections of 3 to separate with commas
var dollar_array:Array = new Array();
var start:Number;
var end:Number = amount_array[0].length;
while (end > 0) {
start = Math.max(end - 3, 0);
dollar_array.unshift(amount_array[0].slice(start, end));
end = start;
}

// assign dollar value back in amount_array with
// the a comma delimited value from dollar_array
amount_array[0] = dollar_array.join(",");

// finally construct the return string joining
// dollars with cents in amount_array
return ("\$" + amount_array.join("."));
}

Thanks for any help

i didn't check that function, but it should be used as follows:
