Argument 1 missing or nil

#1

I want to achieve to load a map when voted on it. Everything works fine but it errors on line 73 when I don’t pick a map.

This is the part where it errors:

function round.LoadMap()
	local votedMap = round.ToggleVoting()
	local mapFolder = ServerStorage.Maps:FindFirstChild(votedMap)
	if not mapFolder then
		mapFolder = ServerStorage.Maps.WheatFields
	end
	
	local newMap = mapFolder:Clone()
	newMap.Parent = workspace.Map

Not sure if it has to do something with FindFirstChild()

#2

I think what it could be is that votedMap is returning nil, may we see ToggleVoting?

#3 
function round.ToggleVoting()
	local maps = ServerStorage.Maps:GetChildren()
	votes = {}
	for i, map in ipairs(maps) do
		votes[map.Name] = {}
	end
	
	info.Voting.Value = true
	
	for i=10, 0, -1 do
		info.VotingTime.Value = "Map Voting... " .. i
		task.wait(1)
	end
	
	local winVote = nil
	local winScore = 0
	
	for name, map in pairs(votes) do
		if #map > winScore then
			winScore = #map
			winVote = name
		end
	end
	
	info.Voting.Value = false
	
	return winVote
end
#4

Which line is line 73? What does the error say?
Edit: nvm just watched the video

#5

From what I see, Each key value pair just has an empty table, nothing is added to the tables of each key, therefore #map is 0, so the condition is never met because 0 is not greater than 0, so winVote is nil,

I think it may be an issue with ToggleVoting itself, what were you trying to do?

#6

This is line 73:

local mapFolder = ServerStorage.Maps:FindFirstChild(votedMap)
#7

So do I need to set winVote to the map?

#8

Nono, The issue is with all of ToggleVoting, you gave each key an empty table value, but you don’t add anything to them, so #map is always 0.

You set winScore to 0, and in the loop you compare 0 > 0 everytime with how the code is set, this condition is never met so winVote is always nil

The entire function needs a change essentially

votedMap returns nil if all the options are tied at 0 votes, and you cannot do :FindFirstChild() with a nil value, so check if it’s not nil before trying to pass it as an arg

function round.LoadMap()
	local votedMap = round.ToggleVoting()

    local mapFolder = ServerStorage.Maps.WheatFields
    if votedMap then
	   mapFolder = ServerStorage.Maps:FindFirstChild(votedMap)
    else

	local newMap = mapFolder:Clone()
	newMap.Parent = workspace.Map

Thanks for the help! I fixed it with an else condition under

if #map > winScore then
