What is a userdata value?

I got this minigame template and out of common sense I was able to start editing and adding maps to make my own minigame series, however when a round is about to end it gets stuck and won't ever finish.

I found this in the output

15:24:47.859 - ServerStorage.Modules.GameHandler:67: attempt to perform arithmetic on local 'points' (a userdata value)

so I went to that line and here's what I found.

module.AwardPlayers = function(val,player)
	if player then
		local stats = player:WaitForChild("leaderstats")
		local points = stats:WaitForChild("Points")
		points = points + val
	else
		for i,v in next, players:GetPlayers() do
			local stats = v:WaitForChild("leaderstats")
			local points = stats:WaitForChild("Points")
			**points = points + val** 
*-- the words in bold were line 67*                                     
		end
	end
end

So I'm trying to find out what userdata value means and if it has anything to do with "val" on line 67.

I think I'll start by asking, what does val mean in lua?

Is it short for value? I'm not so sure because when I changed val to value I got an error.

Out of all my questions you do not have to answer all of them, just if you have any information let me know.

Thanks!

BY THE WAY... Is there any way to make this post look like a text editor? I preview this and it looks like a bunch of paragraphs out of a book. Extremely confusing for sharing entire scripts. I'm afraid I'll have to re-ask this question because people won't be able to separate the lines of script.

I'll give the whole script.

You forgot to add .Value to it, you aren't accessing it's value.

Also to add code here, you need to click the Lua symbol and it should insert in a code block where you can post your code.
