attempt to call a nil value?

Asked Aug 3, 2022235 views2 answers

I am making a horizontal tower of hell like bar but when I test it an error pops up saying "attempt to call a nil value". This is the code where the error occurs:

function Update()
	
	for index, Player in next, PlayerLengthData do
		local xPosition = Player:GetLengthFromEnd()
		
		Player.Frame.Position = UDim2.new(xPosition, 0, 0.5, 0)
	end
	
end

The error is on line 4. I don't know how to fix this error so please help.

Player:GetLengthFromEnd() might not be a valid function, make sure that

it's defined before it's called
it returns a value

How do I know if it returns a value

AnonymousAug 4, 2022#

if your function includes a return line then it will return whatever data is to the right of the return

As the error says, you are attempting to call a nil value, which would be GetLengthFromEnd.
