Help With Adding Player Models to TTT point shop

[Vitre]

I'm trying to add player models to my TTT server and I'm having a really hard time. They show up fine for me, but everyone else either sees giant errors or just the default T model. I have fast dl and i've added them to the workshop.lua. I know this has probably been asked a lot around here, I would really appreciate any help. I've tried about everything i can think of and nothing seems to work.

Harley Quinn Player Model lua

player_manager.AddValidModel( "Harley Quinn", "Models/jessev92/harley_quinn_aa_ply.mdl" ) 
list.Set( "PlayerOptionsModel",  "Harley Quinn", "Models/jessev92/harley_quinn_aa_ply.mdl" )
player_manager.AddValidHands( "Harley Quinn",	"models/jessev92/weapons/arms/harley_quinn.mdl",	0,	"00000000" )

if (SERVER) then
player_manager.AddValidModel( "Harley Quinn", "addons/Harley Quinn Player Model/models/jessev92/harley_quinn_aa_ply.mdl" )
AddCSLuaFile( "addons/Harley Quinn Player Model/lua/autorun/harleyquinn.lua" )
end

list.Set( "PlayerOptionsModel", "Harley Quinn", "addons/Harley Quinn Player Model/models/jessev92/harley_quinn_aa_ply.mdl" )

if ( SERVER ) then
	resource.AddFile ( "harley_quinn_aa_ply.mdl" )
	resource.AddFile ( "weapons/arms/harley_quinn.mdl" )
	resource.AddFile ( "harley_quinn_aa_ply.dx80.vtx" )
	resource.AddFile ( "harley_quinn_aa_ply.dx90.vtx" )

	resource.AddFile ( "harley_quinn_aa_ply.sw.vtx" )
	resource.AddFile ( "harley_quinn_aa_ply.vvd" )
	

pointshop lua

ITEM.Name = 'Harley Quinn'
ITEM.Price = 100000
ITEM.Model = 'C:/Users/Kupo/Desktop/Server/content/garrysmod/addons/Harley Quinn Player Model/models/jessev92/harley_quinn_aa_ply.mdl'

function ITEM:OnEquip(ply, modifications)
if not ply._OldModel then
ply._OldModel = ply:GetModel()
end

timer.Simple(1, function() ply:SetModel(self.Model) end)
end

function ITEM:OnHolster(ply)
if ply._OldModel then
ply:SetModel(ply._OldModel)
end
end

resource.AddFile have to be fed subfolders. models/etc.mdl, materials/etc.model. You're also missing an end after your serverside if statement. Lastly, ITEM.Model is fed a fath relative from models/, not C:/
