for _ in pairs(t) do return true end

is giving me an error (table expected got nil) invalid argument #1 to ‘pairs’
the table exists .
in this situation the table was Equipped[“Weapons”]

This script under , basically is meant to be a equip script , but under circumstances works for unequipping

local function isfilled(t)
	for _ in pairs(t) do return true end
	return false
end


if table.find(Items,Item) then --checks if player has the item unlocked
		

		if  isfilled(EquippedItems[Itemtype] == true then 
			
			EquippedGui:FindFirstChild(itemtype):FindFirstChild(Item).Parent = InventoryGui	
			table.clear(EquippedItems,itemtype)
		
		end	
		
		if itemicon:FindFirstChild("Equipped").Value == false then
			
				itemicon:FindFirstChild("Equipped").Value = true
				table.insert(EquippedItems[itemtype],Item)
			itemicon.Size = UDim2.new(1,0,1,0)
			itemicon.Parent = EquippedGui:FindFirstChild(itemtype)
		else
			itemicon.Parent = InventoryGui
			
			itemicon:FindFirstChild("Equipped").Value = false
			end

This line has two typos:

if  isfilled(EquippedItems[Itemtype] == true then
  1. Did you mean itemtype?
  2. isfilled() doesn’t end with a parenthesis.
#3 
for _ in pairs(t) do return true end

You should use pairs for dictionaries and ipairs for tables instead:

for _,_ in ipairs(t)

Also, your isFilled function can be simplified into

local function isfilled(t)
	return #t > 0
end

yeah , sorry I made a typo in the example code

Table function setting the whole table nil
#5

Hello thanks for the help with the function, I might have found the “real” problem, not sure tho.

I get error ‘attempt to get lenght of a nil value’, at the function, so how does the table somehow become nil, is it the table.clear?

#7

That means that EquippedItems[itemtype] must be nil, i would reccomend verifying the value of itemtype (Did you mean table.find(Items,itemtype) or isfilled(EquippedItems[Item])?)

#8

actually the thing is that I am looking if there is anything the same type already equipped as the thing that is being equipped. (ik you deleted it but still)

#9

is only used to identify if the player owns the item he wants to equip , since its an event on the server, the function is for checking if there is equipped a same itemtype

#10

I was the one who recommended that function, AFAIK from his previously public code t was not an array-like table. # gets the number keys and evaluates to the greatest one, it doesn’t do anything with string keys or whatever type is used.
