Here is the code. I added the hide and Show buttons, they work, but when I run the code and do the start it loads a question and some pictures on to the window. Select the right or wrong answer should result in E1 or E2 showing either a green block or a red X block on top of the item.
It is supposed to wait 1 second before going onto the next question, while showing the right or wrong answer. If you do the right answer it goes to another question. If not, it stays there and waits for you to select the correct answer.
