Machine gun muzzle_flash will not show in game

I am new to Unity and have been following this tutorial on youtube :

http://www.youtube.com/watch?v=sYQQY76F8ac&feature=related

I got to 2:20 in the video and followed EVERY step from there on how to add a gun and muzzle flash but when I shoot in game the muzzleflash only shows in the scene and not in the game window. I took a screenshot of every child that i added to the parent main camera so maybe someone could see a wrong setting or something inside of the inspector.

Also i have not added the sparks animation from the video tutorial yet until i can get this figured out :) I got all of these project folders from the island demo and FPS_Tutorial off the unity website. AND if i cant find a solution for this yet would it be alright to just continue the tutorial and work on this issue later?
