The login code and password are not working
Sometimes the login code and password doesn't work when you copy and paste them from the email, when you manualy enter your code and password you will get access to the questionnaire.

I'm stuck in the questionnaire, I keep returning to the same question. What do I do?
Sometimes, the questions may seem rather similar. A question may be repeated if there has been a minor change, e.g. a brand name or a feature that you are asked to comment on. As a result, you get the impression that the question is being repeated. However, if you really do get stuck in a "loop" and keep returning to the same question over and over again, please contact the helpdesk.

I get a report "server error". What do I do?
It may be that our server (the computer that contains the questionnaire you fill in via the Internet) is overloaded. If this is the case, we ask you kindly to try again later.
