Changing the survey name:
Once you have created a survey you can edit the name by clicking on the edit icon, entering a new name, and then select the green correction mark to make the name change.
Changing the question:
You are also able to make changes to any of the individual questions within the survey by selecting the question and pressing its respective edit button.
Now type in the new or amended question.
Questions can also be re-ordered in a survey by clicking the top bar for each question and dragging it into its new position.
Alternatively, if you have just been doing some testing you can clear the results of the survey. Once results have been cleared you are also then able to edit the content of the survey again.
