(Chances) Players who shouldn't be selected, get selected. Any help?

I am making chances, similar to how MM2 made. This code is acting weird, like the selected player wont get selected, but the other player with no chances gets selected. And usually both players will get selected sometimes. Any ideas why this ain't working?

Code (in Script ServerScriptService):

local Chances = {}

while wait(8) do

repeat wait() until #game.Players:GetPlayers() >= 2
for _,player in pairs(game.Players:GetPlayers()) do
    for i = 1,math.max(1,player.Chance.Value) do
        table.insert(Chances,player.Name)
    end
end

local Choice

for i,v in pairs(game.Players:GetPlayers()) do
	Choice = Chances[math.random(#Chances)]
	if v.Name == Choice then
		v.Chance.Value = 1
		warn(v.Name,"Chances:",v.Chance.Value," SHOULD be selected")
	else
		v.Chance.Value = v.Chance.Value + 1
		warn(v.Name,"Chances:",v.Chance.Value," SHOULD NOT be selected")
	end
end

end

I fixed some common issues. Never use :GetPlayers, Instead use :GetChildren. And don't use while wait() do as it will be very buggy. Don't use warn without a return. Print is a better method anyway. AND as well the script is fixed!

local Chances = {}

while true do
wait(8)
repeat wait() until #game.Players:GetChildren() >= 2
for _,player in pairs(game.Players:GetChildren()) do
    for i = 1,math.max(1,player.Chance.Value) do
        table.insert(Chances,player.Name)
    end
end

local Choice = false --This had to be at least a value!

for i,v in pairs(game.Players:GetChildren()) do
    Choice = Chances -- [math.random(#Chances) Why was this here? It picks the person above anyway.
    if v.Name == Choice then
        v.Chance.Value = 1
        print(v.Name,"Chances:",v.Chance.Value," SHOULD be selected")
    else
        v.Chance.Value = v.Chance.Value + 1
        print(v.Name,"Chances:",v.Chance.Value," SHOULD NOT be selected")
    end
end
