Creating a Survey with multiple Choice

[Philipp Lobo]

Hey there,

for my Masterthesis I have to create a questionnaire which asks for characterisitcs of special practices. It will be answered digital.
To get the most possible number of valid questionnaires - means there are no two answers marked for one question - i want to group the checkboxes so there can be just one answer marked. The questionnaire is attached, it might give you a better impression of what i mean.


I already tried to do it with Active-X but I did not get very far with that, probably because of my limited knowledge about that.

The Question is now: How can I ensure that there can be just one checkbox marked in a row?

Thank you for your help in advance

Greetings
Philipp
