Change Response Type of the Questions

While creating a survey, I accidenttaly selected the multiple response question type (“Select Many”) whereas I had to select (“Select One”) single response question type. Now I am not able to change the response type in the same question. How do I do that?

Download the xlsform of the project. and in the ‘type’ column*(generally the first column). you can change question type for a particular question by deleting ‘select_multiple’ and typing ‘select_one’. after making the change, go to your project and select ‘replace file’. select the xslform file that you just edited.
and you are done. the question should now appear as select-one type.
