Shop gui not working

Help and Feedback Scripting Support
#1

“Attempted to index nil with name.” I’m not sure why this is happening. Appearantly this is where the output error message takes me to. I used alvinblox’s simulator shop model.

local description = game.ServerStorage.ToolModels[item.Name].Information.Description.Value

If you need any more info please tell me.

#2

add the name of the item in between ToolModels. and .Information

Example:

local desc = game.ServerStorage.ToolModels.Gun.Information.Description.Value

yeah that’s mostly it, just make sure the tool has, Information and Description inside of it.

#3

can u send the whole code and a picture the ServerStorage

– Generate blocks

or i can just send you the whole model if you’d like that.

#7

What are u sending in the item parameter when the server is invoked?

#8

local replicatedStorage = game:GetService(“ReplicatedStorage”)
local gui = script.Parent.Parent.Parent
local frame = gui:WaitForChild(“ShopFrame”)
local buy = frame:WaitForChild(“Buy”)
local title = frame:WaitForChild(“Title”)
local description = frame:WaitForChild(“Description”)
local back = frame:WaitForChild(“Back”)
local DISABLED_BUTTON_COLOR = Color3.fromRGB(118, 110, 153)
local ENABLED_BUTTON_COLOR = Color3.fromRGB(255,255,255)
local itemRoller = game.Workspace.ItemRoller

local camera = game.Workspace.CurrentCamera

script.Parent.Activated:Connect(function()

local boxName = script.Parent.Parent.Parent.CurrentBox
local boxToMoveTo = boxName.Value + 1

if game.Workspace.ItemRoller:FindFirstChild(“Box”…boxToMoveTo) then
– There is a box for when we click the back button

  local tween = game:GetService("TweenService"):Create(
  	camera,
  	TweenInfo.new(0.5, Enum.EasingStyle.Quad, Enum.EasingDirection.In,0,false,0),
  	{
  		CFrame = game.Workspace.ItemRoller["Box"..boxToMoveTo].CamPart.CFrame,
  		Focus = game.Workspace.ItemRoller["Box"..boxToMoveTo].Hitbox.CFrame
  	}
  )

  tween:Play()



  boxName.Value = boxName.Value + 1
  
  
  local model = nil

  for i, object in pairs(itemRoller["Box"..boxName.Value]:GetChildren()) do
  	
  	if object:IsA("Model") then
  		model = object
  		frame.ModelName.Value = object.Name
  	end
  	
  end
  
  local data = replicatedStorage.RequestInformation:InvokeServer(model)
  
  for i, v in pairs(data) do
  	print(v)
  end
  
  title.Text = tostring(data[1])
  description.Text = tostring(data[2])
  
  if data[5] == false then
  	buy.Text = "$"..tostring(data[3])
  end

else
print(“ah”)

  end

end)

im pretty sure that’s where the function is being invoked.

#9
