Format Currency value with thousand seprator

Hi All,

I have a script portlet which is loading a currency value from a custom record, I want to display the value formatted correctly for currency i.e 13210.00 13,210.00.

I have looked at this page http://josscrowcroft.github.io/accounting.js/ which has a script file that can be used but I am having trouble calling it into my script to use it's function.  Is it even possible to call a function from another .js file in Netsuite suitescript??

Any help gratefully received.  My Code below for the portlet.

function ASIP_NEW(portlet, column)     {   portlet.setTitle('Assessment Services Information - New')     //var today = new Date();      var today = new Date();      var date = today.getDate();   var Month = today.getMonth();      nlapiLogExecution('DEBUG', 'Date', date );   nlapiLogExecution('DEBUG', 'Month', Month );        //Start Of Details Capture      if (Month == 0)    {    //Get Month 0 Record - January    var MonthRecID = 1;    }   if (Month == 1)    {    //Get Month 1 Record - February    var MonthRecID = 2;    }   if (Month == 2)    {    //Get Month 1 Record - March    var MonthRecID = 3;    }   if (Month == 3)   {   //Get Month 1 Record - April   var MonthRecID
