I cannot see a screen where I can enter the user number and the access code.
This may have several causes. 1) You have typed the web address into a search engine (e.g. Google). Unfortunately, that does not work. Because your data is confidential, Statistics Netherlands uses a secure server. Type the link directly in the address bar of your browser. 2) You forgot the 's' after 'http' when typing the web address. 3) You cannot access the internet. Try a different website and see if it works. You may have problems with your network connection.
