SWEP shooting sound won't work

Alright so today I attempted to make a swep, its pretty sick but the sound wont work!
Here is the code I used for the sound,

SWEP.Primary.Sound			= "sound/thompson/tshoot.wav"

I have the sound located in the sweps folder in sound/thompson so it should work, but it isn’t.
Help please?
