Step 1

Program what happens when the NextButton is clicked. Get the event handler block for this event.

Step 2

When the NextButton is clicked, the following things should happen:

• Increase the Index Variable by one
• Change the picture, according to the PictureList Variable
• Change the question text, according to the QuestionList Variable

To do this, create this code:



The code uses the Index Variable to keep track of the question number. 

Step 3

Try the code on your phone now! Click the Next button to change the picture and the question. What happens if you keep pressing next?

Step 4

You got an error! This is because you got to the end of the list and the program didn’t know what to do.

Step 5

Test the code again! The quiz will now go back to the start!
