Java Query to retrieve account(s) is failing

The query below was working and I needed to modify it to only retrieve active accounts.

I added the addition portion of the StateCode check. (In Red below)

When this runs, it errors out stating that there is a syntax error.  What did I do wrong?

function retrieveAccounts(accountNumberIdentifier, businessUnit)

{

   var accountNumber = Xrm.Page.getAttribute(accountNumberIdentifier).getValue();

   var businessUnitValue = GetBusinessUnitValue( businessUnit );

   totalAccountCount = 0;

   var serverUrl = getServerUrl();

   var accountQueryUrl = getQueryString(accountNumber, businessUnitValue, serverUrl);

   var retrievedAccounts = getODataRecords(accountQueryUrl);

                totalAccountCount = retrievedAccounts.results.length;

}

function getQueryString(accountNumber, businessUnitValue, serverUrl)

{

                var options = "$select=AccountNumber,fgs_BusinessUnit,CustomerTypeCode&"

                +"$filter=AccountNumber eq '" + accountNumber

                + "' and fgs_BusinessUnit/Value eq " + businessUnitValue

                + " and CustomerTypeCode/Value eq " + CUSTOMER_VALUE

               + “ and StateCode eq 0”;

   var ODataPath = serverUrl + "/XRMServices/2011/OrganizationData.svc";

   var queryUrl = ODataPath + "/AccountSet?" + options;

                return queryUrl;

}
