attempt to index upvalue "inventory"?

I'm doing the inventory GUI and it should render the objects, but it doesn't know what the inventory is! Here's the error.

    13:58:10.632 - Players.HDWC.PlayerGui.MainHUD.HUD Handler:97: attempt to index upvalue 'inventory' (a nil value)

13:58:10.633 - Stack Begin

13:58:10.633 - Script 'Players.HDWC.PlayerGui.MainHUD.HUD Handler', Line 97

13:58:10.634 - Stack End

The local script

--VAIRIABLES

local hud = script.Parent

local inventory_frame = hud.Inventory

local inventory_holder = inventory_frame.Inventory_Holder



local inventory_search = inventory_frame.Search

local inventory_x = inventory_frame.X



local inventory = events.GetInventory:InvokeServer()

local leftholder = script.Parent.LeftHolder

local inventory_button = leftholder.Inventory

local tab_opener = require(script["Tab Opener"])



--FUNCTIONS

function renderinventory()

local function renderobject(item_name)

local frame = script.UiTemplate:Clone()

frame.Title.Text = item_name

local camera = Instance.new("Camera", frame)

frame.CurrentCamera = camera

local item = items:FindFirstChild(item_name):Clone()

item.Parent = frame

item:SetPrimaryPartCFrame(CFrame.new(0,0,0))

camera.CFrame = CFrame.new(Vector3.new(6,2,12), item.HitBox.Position)

return frame

end

local objects = inventory:GetChildren()

for _, v in pairs(objects) do

local frame = renderobject(v.Name)

frame.Parent = inventory_holder

end

end



--STARTUP



local signal = tab_opener:EnableObject(inventory_button, inventory_frame, UDim2.new(0.8,0,0.8,0), inventory_x)

signal:Connect(renderinventory)

And finnally the server script:

--Vairiables

local players = game:GetService("Players")

local bases = workspace.Bases

local items = game:GetService("ReplicatedStorage").Items

local events = game:GetService("ReplicatedStorage").Events

local dataservice = game:GetService("DataStoreService")

local data = require(script.SaveData)

local sstorage = game:GetService("ServerStorage")

local pinventory = sstorage:WaitForChild("PlayerInventory")



--Functions



function get_base(Player)

return bases.Base01

--[[

local returnvalue

for _, v in pairs(bases:GetChildren()) do

if v.Owned == nil or v.Owned == Player then

returnvalue = v

if v.Owned == nil then

v.Owned = Player

end

return returnvalue

end

end

--]]

end



function placeobject(player, location, model, base)

local itemTemplate = items:FindFirstChild(model)



if (itemTemplate) then



local item = itemTemplate:Clone()

item.Parent = base.ItemHolder

item:SetPrimaryPartCFrame(location)



end

end



function loadsave(plr)

createinventory(plr)

for i, v in pairs(data.Load(plr, get_base(plr))) do

placeobject(plr, v[2], v[1], get_base(plr))

end

end



function createinventory(plr)

local f = Instance.new("Folder", pinventory)

f.Name = plr.Name

return f

end

function get_inventory(plr)

return pinventory.HDWC

end

--Startup



--Triggers



players.PlayerAdded:Connect(loadsave)

players.PlayerRemoving:Connect(function(plr)

data.Save(plr, get_base(plr))

end)



events.GetBase.OnServerInvoke = function(plr)

return get_base(plr)

end

events.GetInventory.OnServerInvoke = function(plr)


return get_inventory(plr)

end



events.Place.OnServerEvent:Connect(function(plr, location,model, base)

placeobject(plr, location,model, base)

end)

Thanks in advance
