I need help fixing this

[mandog236]

Okay, so I'm trying to fix this error in an old version of drugs mod. I'm trying to make it so that using cocaine makes you go faster.
I will highlight the code that I think should, but does not work. Please help me fix :[

AddCSLuaFile("shared.lua")
include("shared.lua")

ENT.MODEL = "models/cocn.mdl"

ENT.MASS = 2; --the model is too heavy so we have to override it with THIS

ENT.LASTINGEFFECT = 45; --how long the high lasts in seconds

function ENT:High(activator,caller)
--cut health in half and double the speed
activator:SetHealth(activator:Health()/2)
if( activator:Health() > 1 )then
self:Say(activator, "MYNOSEISDRIBBLINGISANYONEELSESNOSEDRIBBLINGTHATSREALLYWEIRDIHOPEIDONTHAVEACOLD")
end

[B]self.MakeHigh = false;
local ss = activator:GetNetworkedFloat("SprintSpeed")
local ws = activator:GetNeworkedFloat("WalkSpeed")
if activator::GetNetworkedFloat("durgz_cocaine_high_end") < CurTime() && ( !activator:GetNetworkedFloat("durgz_oldSprintSpeed") || activator:GetNetworkedFloat("durgz_oldSprintSpeed") == 0 || activator:GetNetworkedFloat( "durgz_oldSprintSpeed") == ss ) then
self.MakeHigh = true;
end[/B]
function ENT:AfterHigh(activator, caller)

--kill them if they're weak
if( activator:Health() <=1 )then
activator.DURGZ_MOD_DEATH = "durgz_cocaine";
activator.DURGZ_MOD_OVERRIDE = activator:Nick().." died of a heart attack (too much cocaine).";
activator:Kill()
return
end

local ss = activator:GetNetworkedFloat("SprintSpeed")
local ws = activator:GetNetworkedFloat("WalkSpeed")
if( self.MakeHigh )then
activator:SetNetworkedFloat( "durgz_oldSprintSpeed", ss)
activator:SetNetworkedFloat( "durgz_oldWalkSpeed", ws)

activator:SetRunSpeed(ss*6)
activator:SetWalkSpeed(ws*6)
end
end

--set speed back to normal once your high is over
local function ResetSpeed()
for id,pl in pairs(player.GetAll())do

if pl:GetNetworkedFloat("durgz_cocaine_high_end") < CurTime() && pl:GetNetworkedFloat("durgz_cocaine_high_end") + 0.5 > CurTime() && ( pl:GetNetworkedFloat( "durgz_oldSprintSpeed" ) && pl:GetNetworkedFloat("durgz_oldSprintSpeed") != 0)then
pl:SetWalkSpeed(pl:GetNetworkedFloat( "durgz_oldWalkSpeed" ))
pl:SetRunSpeed(pl:GetNetworkedFloat( "durgz_oldSprintSpeed" ))
end

end
end
hook.Add("Think", "durgz_cocaine_resetspeed", ResetSpeed)

function ENT:SpawnFunction( ply, tr )

if ( !tr.Hit ) then return end

local SpawnPos = tr.HitPos + tr.HitNormal * 16

local ent = ents.Create("durgz_cocaine")
ent:SetPos( SpawnPos )
ent:Spawn()
ent:Activate()

return ent
end
