My AliveChecker that consists of conditionals and loops isn't working, help?

What I'm trying to do is that for every single player it's going to run through a series of checks, and if they are dead or they left the game they are counted as not alive and then they are removed from a table.

for x,v in pairs(plrs) do
	if v then
		local Character = v.Character
		if not Character then
			table.remove(AlivePlayers,x)
		else
			if Character:FindFirstChild("Alive").Value then
				print(Character.Name.." is still alive.")
			else
				table.remove(AlivePlayers,x)
			end
		end
	else
		table.remove(AlivePlayers,x)
	end
end
		

I believe, I may not be correct, go easy... But I believe your issue lies on line 07 your if statement hasn't specified exactly what you're hoping 'Alive' is to equal, sometimes silent outputs consist of synax related problems, honestly if this statement was to run, It wouldn't matter what it equals, as long as Alive is equal to what it is, go through with it. So I suggest writing it like so

01
for Placement,Players in ipairs(plrs) do
    if v them
        local Character = Player.Character or Player.CharacterAdded:wait() --// more efficient
        if not Character then
            table.remove(AlivePlayers,Placement)
        else
            if Character:FindFirstChild("Alive").Value ~= false then
                print("'"..Player.Name.."' is still alive.")
            else
                table.remove(AlivePlayers, Player, Placement)
            end
        end
    else
        table.remove(AlivePlayers, Player, Placement)
    end
end

You may have noticed I've spruced it up just a bit, some more efficient methods, like ipairs.

I also may not exactly be an expert at table looping, yet I believe the second argument of the table consists of the instance, not the index, the third is also an optional choice, if not, then just revert it, or try switching 'Placement' to Player instead?

Hope this works, again go easy on me, if everything works out, don't forget to acept the answer and upvote, help me help you:)
