Hi.. I would attach the file on the comment.
It took one week that I have inserted the sound effect. it's too complicate to explain it.
That is, there are two parts that are my project and Peter project. But when I have inserted two parts, it's messed up. I didn't find it out after all. as you see the file, you can check just Peter part Sound.
Which means I can insert the sound of my part without Peter part sound.
If you have good idea, let me know
