Restrict for login

Please help and give me some advice. The due date for my project is around the corner.

I faced the "Restrict Access to page" function problem although i follow all steps to create login page to restrict page. The problem is when the 2 access level person who are administrator and user login, the login page will redirect to the access denied page. The administrator level person should redirect to the page that i had set Restrict Access To Page.

I had chosen the Restrict access base on username, password and access level, and get level from "database". Then for the Restrict Access To Page function at the Restrict page, I had chosen username,password, and access level. At Selects Level(s), there are adminstrator and user which follow the name of the access level field in the database. I selected administrator and set the access denied page.

I had found an error when i click on the Live Data View button. It pop up a message, "Live Data Error: an error occured while requesting the document from the testing server" on the restrict page. But I also cannot find the solution.

Please help...

Thanks in advance.
