Custom SWEP sound help

Hi there!
Am working on a SWEP pack and i got some problems with the custom sounds. They work but some of the sounds aply on the regular css sounds. For example my M4 w. M203 clipin and clipout sound aplies on the regular m4 sounds that came with gmod.
So here is a example from the script file or what ever:

// VOL_NORM 1.0f

// Channels
// CHAN_AUTO = 0,
// CHAN_WEAPON = 1,
// CHAN_VOICE = 2,
// CHAN_ITEM = 3,
// CHAN_BODY = 4,
// CHAN_STREAM = 5, // allocate stream channel from the static or dynamic area
// CHAN_STATIC = 6, // allocate channel from the static area
// these can be set with “channel” “2” or “channel” “chan_voice”

//-----------------------------------------------------------------------------
// common attenuation values
//-----------------------------------------------------------------------------

// DON’T USE THESE - USE SNDLVL_ INSTEAD!!!
// ATTN_NONE 0.0f
// ATTN_NORM 0.8f
// ATTN_IDLE 2.0f
// ATTN_STATIC 1.25f
// ATTN_RICOCHET 1.5f
// ATTN_GUNFIRE 0.27f

// SNDLVL_NONE = 0,
// SNDLVL_25dB = 25,
// SNDLVL_30dB = 30,
// SNDLVL_35dB = 35,
// SNDLVL_40dB = 40,
// SNDLVL_45dB = 45,
// SNDLVL_50dB = 50, // 3.9
// SNDLVL_55dB = 55, // 3.0
// SNDLVL_IDLE = 60, // 2.0
// SNDLVL_TALKING = 60, // 2.0
// SNDLVL_60dB = 60, // 2.0
// SNDLVL_65dB = 65, // 1.5
// SNDLVL_STATIC = 66, // 1.25
// SNDLVL_70dB = 70, // 1.0
// SNDLVL_NORM = 75,
// SNDLVL_75dB = 75, // 0.8
// SNDLVL_80dB = 80, // 0.7
// SNDLVL_85dB = 85, // 0.6
// SNDLVL_90dB = 90, // 0.5
// SNDLVL_95dB = 95,
// SNDLVL_100dB = 100, // 0.4
// SNDLVL_105dB = 105,
// SNDLVL_120dB = 120,
// SNDLVL_130dB = 130,
// SNDLVL_GUNFIRE = 140, // 0.27
// SNDLVL_140dB = 140, // 0.2
// SNDLVL_150dB = 150, // 0.2

//M4 sOPMOD

“Weapon_M4sm.Single”
{
“channel” “CHAN_ITEM”
“volume” “1.0”
“CompatibilityAttenuation” “1.0”
“pitch” “95,105”

"wave"			"weapons/m4sm-1.wav"

}

“Weapon_M4A1.Clipout”
{
“channel” “CHAN_ITEM”
“volume” “1.0”
“CompatibilityAttenuation” “1.0”
“pitch” “PITCH_NORM”

"wave"			"weapons/m4sm_clipout.wav"

}

“Weapon_M4A1.Clipin”
{
“channel” “CHAN_ITEM”
“volume” “1.0”
“CompatibilityAttenuation” “1.0”
“pitch” “PITCH_NORM”

"wave"			"weapons/m4sm_clipin.wav"

}

So what the hell am i doing wrong??? I tried every thing and still it aplies on the regular sounds… help?
