I have written the code like this in the sender configuration of email client configuration, selecting script in From Generation Type, it is not working. Please let me know any one can help.

(function(fromAddressQuery, targetRecord) {

    /**

     * fromAddressQuery: A GlideRecord on the table "sys_email_client_from_address". Add conditions to filter the

     *      the email addresses displayed in the Email Client.

     * targetRecord: A GlideRecord representing the record in which the Email Client was opened from

     */

    var userGr = new GlideRecord('sys_user');

    userGr.addQuery('sys_id', current.assigned_to);

    if (userGr.next()) {

        answer = userGr.email;

    }

})(fromAddressQuery, targetRecord);
