Need SWEP:PrimaryAttack() Coded

[Andriko1]

Hi, I'm pretty bad at coding sweps xD which is why I'm posting here, can someone code a SWEP:PrimaryAttack() function? For reference on how I want it here is my failed SWEP:PrimaryAttack() function.

[lua]
function SWEP:PrimaryAttack()

if ( self.ShootafterTakeout > CurTime() ) then return end
self.Weapon:SetNextPrimaryFire( CurTime() + .4 )

local ply = self.Owner
local pos = ply:GetPos()
local ang = ply:GetAimVector()
local phtr = ply:GetEyeTrace()
local trace = util.TraceHull( tracedata )
local tr = util.TraceLine(trace)
local ph = phtr.Entity:GetPhysicsObject()

if (ply:GetPos() - tr.HitPos):Length() < 100 then

if tr.Entity:IsPlayer() or string.find(tr.Entity:GetClass(),"npc") or string.find(tr.Entity:GetClass(),"prop_ragdoll") or tr.Entity.MatType == "MAT_GLASS" then

if self.hit == 1 then
self.Weapon:EmitSound( self.FleshHit1 )
self.hit = 2

elseif self.hit == 2 then
self.Weapon:EmitSound( self.FleshHit2 )
self.hit = 3

elseif self.hit == 3 then
self.Weapon:EmitSound( self.FleshHit3 )
self.hit = 4

else
self.Weapon:EmitSound( self.FleshHit4 )
self.hit = 1
end

ply:SetAnimation( PLAYER_ATTACK1 );
self.Weapon:SendWeaponAnim( ACT_VM_PRIMARYATTACK );

local startpos = self.Owner:GetShootPos()
local endpos = startpos + self.Owner:GetAimVector() * 75
local minbox = Vector(-10,-10,-10)
local maxbox = Vector(10,10,10)
local damage = 15
local dtype = DMG_SLASH
local dforce = 5
local damageall = true
self.Owner:TraceHullAttack(startpos, endpos, minbox, maxbox, damage, dtype, dforce, damageall)

else
util.Decal("ManhackCut", tr.HitPos + tr.HitNormal, tr.HitPos - tr.HitNormal)
self.Weapon:EmitSound(self.WallSound,100,math.random(95,110))
self.Weapon:SendWeaponAnim(ACT_VM_PRIMARYATTACK)
if not tr.HitWorld and not string.find(tr.Entity:GetClass(),"prop_static") then
if SERVER then ph:ApplyForceCenter(self.Owner:GetAimVector()*5000) end
end
end

else
self.Weapon:EmitSound(self.MissSound,100,math.random(90,120))
self.Weapon:SendWeaponAnim(ACT_VM_PRIMARYATTACK)

end

self.Owner:SetAnimation( PLAYER_ATTACK1 ) --3rd Person Animation

end
[/lua]

Thanks
