address fields on before submit create

Hi,

When I create a record my script is not finding the address variables. When I edit it the code works fine.

I tested this by hardcoding the address variables in my script at which point it worked on create.

Example of create (not working)

if (type == 'create' || type == 'edit')   {    var record = nlapiGetNewRecord();        //need to lookup: city, state, zipcode    var customerCity = record.getFieldValue('billcity');    var customerState = record.getFieldValue('billstate'); 

Example hard coded which works on create

if (type == 'create' || type == 'edit')   {    var record = nlapiGetNewRecord();        //need to lookup: city, state, zipcode    var customerCity = 'chicago';    var customerState = 'illinois';
