Matchmaking Error? [Cannot Set a Player's Name??]

Here's the script, so I'm taking two players from the server and adding them to a tournament board. I've been getting this error. Please help.

local ss = game:GetService("ServerStorage")
local values = ss:WaitForChild("Values")
local ingame = values:WaitForChild("In-Game")
local display = ingame:WaitForChild("display")
local countdown = ingame:WaitForChild("countdown")

local playerfolder = ss:WaitForChild("PlayerFolder")
local playercount = ss:WaitForChild("PlayerCount")

local tourneyboard1 = workspace:WaitForChild("TournyBoard")
local tourneyboard2 = workspace:WaitForChild("TournyBoardd")
local tourneyboardgui1 = tourneyboard1:WaitForChild("Gui")
local tourneyboardgui2 = tourneyboard2:WaitForChild("Gui")
local tourneyframe1 = tourneyboardgui1:WaitForChild("Frame")
local tourneyframe2 = tourneyboardgui2:WaitForChild("Frame")

while true do
    if playercount.Value >= 3 then
        while true do
            for i = 20,0,-1 do
            display.Value = 'Welcome! The game will begin shortly. Time Left: '..i
            wait(1)
        end
        wait(3)
        display.Value = "Welcome to LukeGabriel's 1 on 1 Basketball Tournament."
        wait(3)
        display.Value = "Starting game..."
        wait(3)
        display.Value = "Adding Players to the Tournament Bracket."
        local players = game.Players:GetChildren()
        math.randomseed(tick())
        local Chosen1 = players[math.random(1,#players)]
        local Chosen2 = players[math.random(1, #players)]
        repeat Chosen2 = players[math.random(1, #players)] until Chosen2 ~= Chosen1
        local player1 = tourneyframe1:WaitForChild("Text001")
        local playerr1 = tourneyframe2:WaitForChild("Text001")
        local player2 = tourneyframe1:WaitForChild("Text002")
        local playerr2 = tourneyframe2:WaitForChild("Text002")
        Chosen1.Name = player1.Text --what would i put here???
        Chosen1.Name = playerr1.Text
        Chosen2.Name = player2.Text
        Chosen2.Name = playerr2.Text
        math.randomseed(tick())
        local Chosen3 = players[math.random(1, #players)]
        local Chosen4 = players[math.random(1, #players)]
        repeat Chosen3 = players[math.random(1, #players)] until Chosen3 ~= Chosen4 or Chosen2 or Chosen1
        local player3 = tourneyframe1:WaitForChild("Text003")
        local playerr3 = tourneyframe2:WaitForChild("Text003")
        local player4 = tourneyframe1:WaitForChild("Text004")
        local playerr4 = tourneyframe2:WaitForChild("Text004")
        Chosen3.Name = player1.Text
        Chosen3.Name = playerr1.Text
        Chosen4.Name = player2.Text
        Chosen4.Name = playerr2.Text
        display.Value = "Game will begin."
    wait(10)
    end

    else
        display.Value = "Game does not have enough players. " .. 3 - playercount.Value .. " players needed."
        end
    wait()
end

I've also tried players[Chosen1].Name, but that doesn't work either.
