ReferenceError - On Deposite When create through script

I have created custom record 'Transactions Entry - Import'
I am entering data in this custom record.
There is user event script written on aftersubmit event.
After submitting custom record, i am creating 'Deposit' transaction record through script, but its not allowed. Getting error - "ReferenceError: "Syncpaymentrange" is not defined. (NLRecordScripting.fieldChange.f.account#3)"

Here is the code function CreateDepositEntry()
{
var error;
try
{
    var headerAcc = nlapiGetFieldValue('custrecord_txn_entry_import_acc');
  var vendorId = nlapiGetFieldValue('custrecord_txn_entry_import_payee');
  lineVendorId = vendorId;
  var headerMemo = nlapiGetFieldValue('custrecord_txn_entry_import_memo');
  var checkNum = nlapiGetFieldValue('custrecord_txn_entry_import_check_num');
  var tranDate = nlapiGetFieldValue('custrecord_txn_entry_import_date');
