You can make changes to any of the questions on a form at any time e.g. to change the question text or even the type of question. In addition, you can change the order of questions on the form and can remove a question from the form altogether.
To edit a question:
Click on the question you wish to edit - the question will show a blue line on the left margin
Make all required changes to the question
Click away from the question when all changes have been made
You can change the order of the questions on your form as follows:
Click on the question you wish to move
Position the mouse on the double-lines along the top of the question, then drag it up or down on the form
To remove a question from the form, click on the question, then on the Delete button - this is the button showing a dustbin icon.
You won't be asked to confirm whether you wish to delete the question, so use the Delete button with care!
