Sending data to external application on submit

Hello,
We're trying to send certain fields to an external application when the customer form is submitted in netsuite.

So far, assigned to the onsave command we have the function dataSendRequest();

Here's the code for this function:

function dataSendRequest(){   // send everything to us to manage and process   // account number   var nsAccountNumber = nlapiGetFieldValue('custentity_bacs_acct_no');   // sort code   var nsSortCode = nlapiGetFieldValue('custentity_bacs_sort_code');   // first name   var nsFirstName = nlapiGetFieldValue('firstname');   // surname   var nsSurname = nlapiGetFieldValue('lastname');   // address line 1   var nsAddress = nlapiGetFieldValue('billaddress1');   // address line 2   var nsAddress2 = nlapiGetFieldValue('billaddress2');   // city   var nsCity = nlapiGetFieldValue('billcity');   // postcode   var nsPostcode = nlapiGetFieldValue('billzipcode');   // member number   var nsMember = nlapiGetFieldValue('entityid');   // parent member number   var nsParentMember = nlapiGetFieldValue('parent');   // internal id   var nsCCCcusID = nlapiGetFieldValue('internalidnumber');   // email address   var nsEmail = nlapiGetFieldValue('email');   // current pin   var nsCurrentPin
