What is conditional branching?

Basically instead of displaying the questions in order, the next question could branch off in more than one direction depending on the answer chosen. If you look at our demo, if you answer yes to the first question "Is this the first time you have used us?", the second question will be "How did you hear about us?", if you answer no, the second question will be "Why did you choose to use us again?". You can skip questions depending on the answers.
This is achieved by entering the "Next Question ID" next to the answer you wish to trigger the branching. Some question types such as text only have one "Next Question ID", this basically allows you to skip questions, or if you enter -1 it will end the survey.
