You can edit a question you have already created by going to the Questions tab. Place your mouse over the question that you would like to edit. Once you do this a few grey option buttons will appear. Click the Edit button to open the question and make changes. Note that editing will not allow you to change the question type. If you need to change the question type, it is suggested that you create a new question with the desired question type, then go back and delete the original question you are replacing.
