My simple script died all of the sudden!! What gives??

Hi-

This script look up the default expense account and our account number when entering vendor bills... It was working great, but now it causes the enter bill screen to lock up and act erratic... Any ideas?



function vendorinfo()
{
var tvendorintid = nlapiGetFieldValue('entity');
var custacct = nlapiLookupField('vendor', (tvendorintid*1), 'accountnumber');
nlapiSetFieldValue('custbody_custacctnum', custacct, false);

var record = nlapiLoadRecord('vendor', tvendorintid);
var expenseaccountValue = record.getFieldValue('expenseaccount');

var record2 = nlapiLoadRecord('account', expenseaccountValue);
var EAname = record2.getFieldValue('acctname');
var EAnum = record2.getFieldValue('acctnumber');
var EAfinal = (EAnum+" - "+EAname);
nlapiSetFieldValue('custbody_expaccntnum', EAfinal, false);

return true;
}
