MySQLi User Access cant do single login user levels like this.
You would need to create a Login for each user level. In the login behavior, the first ssetting is to set the login name. Use a unique nale for each login.
On the Find Record Tab, set it to filter the Username and Password columns on the login form elements, for the user level, enter the user level value Admin for the admin login and Member for the member login, etc.
When applying the restrict access behavior to a page, select the corresponding login name.
