Name translates to nil

I am trying to create some item Gui’s based on a list of items, however, the name I give the Gui is nil even after it prints the correct name.

Here is my (local) script:

local itemModule = require(game.ReplicatedStorage.ModuleScripts.CreateItems)

local items = itemModule.craftableItems

local function unloadItems(itemsTable)
	for i, v in pairs(itemsTable) do
		local split = string.split(v, ",") -- "3 wood", "1 stone"
		local numberOfTypesOfItems = #split -- 2
		
		local gui = game.ReplicatedStorage.Ui.ItemSample
		if gui then
			local newGUi = gui:Clone()
			newGUi:FindFirstChild("ItemName").Text = i
			newGUi.Name = i 
			
			for index, value in pairs(split) do
				local deepSplit = string.split(value, " ")
				local number = deepSplit[1]
				local name = deepSplit[2]
				print(number, name)
				
				if newGUi and name and number then
					local intvalue = Instance.new("IntValue")
					intvalue.Name = name
					intvalue.Value = number
					
					intvalue.Parent = newGUi
					newGUi.Parent = script.Parent
				else
					return false
				end
			end
		end
	end
end

local unload = unloadItems(items)
if not unload then
	print("Error when unloading items to craft!")
end

The module script (if you need it)

local items = {
	craftableItems = {
		["Wood Planks"] = "3 Wood",
	}
}



return items

Here is the print, in the output:

This might be the reason, newGui, name, and number are probably not nil and so it is not returning anything from the function, which therefore, makes unloadItems(items) equal to nil.

Is this intended behavior or not?

Your module doesn’t return anything and the bottom line checks if what unload returns is falsy. Both false and nil are falsy and will fail the if statement because of the not. Change your not condition to check if false is explicitly returned and you’ll no longer have this happen.

if unload == false then
    print("Error when unloading items to craft!")
end

Not really proper error handling but I won’t really ask too deeply.

Thanks for your reply. However, I return true once the function (if it does) runs smoothly. Thus, the function should be true. I do not see any way this could become false. I will try your idea though.

#5

Wait…I do not return true once the function is done…

#6

Why do you say it like that?

#7

It’s a term used to describe a condition where something is considered false in a boolean context. If you’ve heard of truthy or truthiness, falsy or falsiness is the opposite of that. If I don’t say falsy it changes what I say completely because now I’m referring to only false. nil is not false but it is falsy.

In writing:

→ Your module doesn’t return anything and the bottom line checks if what unload returns is false.

This would be incorrect because false is not the only value being checked by an if not (condition) then statement, it checks if the condition is anything but true (existing). False and nil both fail the if statement because of the not there. They’re the opposite of existing.
