I'm trying to create a quick custom login page for our customer center. I followed the directions here: https://system.na2.netsuite.com/app/help/helpcenter.nl?fid=section_4706661761.html I've made sure post action field is correct. (/app/login/secure/privatelogin.nl?c=<AccountID>) I also have only the following input fields on my login form: email, password, submit. Even so, I still get this message every time I attempt to log in: "Notice URL is missing the id parameter. The file could not be retrieved."
