trouble with a checkbox on the user registration pages I created an extra checkbox field for the user registration form

This is the field setting page. (Standaardwaarde means "Default value.")



In the setting page, the field is unchecked, but it's checked in the registration page. I looked at some older questions regarding this subject, but it still a big questions mark for me. 

How can I get the checkbox to be unchecked by default?
Found the answer. The problem was that I selected the wrong field type. I think because it is only one field you need to select a Boolean type. Now it's working!
