Script to update sub customer address field

Anyone can take alook and see what wall we are hitting.
We are trying to update the subcustomer address field when the parent address field gets changed.. Any suggestions would be great.

thanks in advance here is the code


function NewAddress()
{
  var pInternalId = nlapiGetRecordId();
 
  var pAddress1 = nlapiGetFieldValue('address1');
  var pAddress2 = nlapiGetFieldValue('address2');
  var pCity = nlapiGetFieldValue('city');
  var pZipCode = nlapiGetFieldValue('zipcode');
  var pCountry = nlapiGetFieldValue('country');
  var pState = nlapiGetFieldValue('state');
 
  var filters = new Array();
  filters[0] = new nlobjSearchFilter('parent',null,'is',pInternalId,null);
 
  var columns = new Array();
  columns[0] = new nlobjSearchColumn('internalid');
  columns[1] = new nlobjSearchColumn('address1');
  columns[2] = new nlobjSearchColumn('address2');
