To someone concerned,
I have two questions in this program attached:
How could I let the car1 go to disk2, disk3, disk4… when I finish the slide 2-6 and click the go-back button, one by one?
Why the disk-flash gif couldn’t run in this grogram?

Dear Toan Le,
Thanks for your great help. I have fix all the problems by your instructions. The attached file is the final edition.
And now, I have another question, if the students choose the wrong answer anytime, how could I let the car go backward one step?
I’ve answered your email.
