Arduino - audio playback - ultrasonic sensors

[annaharutyunyan]

Hi Dear friends .
We have a project with arduino, but it works wrong. We have three Ultrasonic sensors, one CD card and one audioplayer. We need to read the file from CD and send it to the audioplayer everytime at least one of ultrasonic sensors detects movement.
You can see my code below. It doesn't work correct. Please, if it's possible help to find my mistake or suggest me another code.
Thanks a lot for your time.

We’ll be looking forward to hearing from you!

Best regards,
