ScreenGui is not a member of PlayerGui??

This error came from two scripts.

1st Script:

wait(1)
while game.ServerScriptService.Playing.AlivePlayers.Value > 0 do        
    local list = workspace.Map.CS:GetChildren()
    m = list[math.random(#list)]
    for i, v in pairs(game.Players:GetChildren())do
        v.PlayerGui.ScreenGui.ColorFrame.Frame.BackgroundColor3 = m.Color
        v.PlayerGui.ScreenGui.ColorFrame.ColorName.Text = m.BrickColor.Name
    end
    wait(7)
    for i, v in pairs(workspace.Map.CS:GetChildren())do
        if v.BrickColor.Name ~= m.BrickColor.Name then
    v.CanCollide = false
    v.Transparency = 0.7
end
    end 
    wait(3)
    for i, v in pairs(workspace.Map.CS:GetChildren())do
    v.CanCollide = true
    v.Transparency = 0
        v.BrickColor = BrickColor.Random()
    end
end
repeat wait(1) until game.ServerScriptService.Playing.AlivePlayers.Value <= 0
game.ServerScriptService.Main.Disabled = true
    for i, v in pairs(game.Players:GetChildren())do
        v.PlayerGui.ScreenGui.ColorFrame.Visible = false
        v.PlayerGui.ScreenGui.TextLabel.Visible = true
        game.ReplicatedStorage.Text.Value = "Nobody Survived!"
    end
    wait(5)
    workspace.Map:ClearAllChildren()
    game.ServerScriptService.Main.Disabled = false
    script.Disabled = true

2nd Script:

local text = game.ReplicatedStorage.Text

    for i = 25, 0, -1 do
        text.Value = "Next Round in "..i
        wait(1)
    end
    wait(2)
        text.Value = "Picking Gamemode..."  
        wait(5)
        local gamemode = math.random(1)
        if gamemode == 1 then
            game.Lighting.CS:Clone().Parent = workspace.Map
            for i, v in pairs(workspace.Map.CS:GetChildren())do
                if v:IsA("BasePart") then
                v.BrickColor = BrickColor.Random()
                end
            end
            text.Value = "The gamemode will be Color Scramble!"
            wait(3)
            game.ServerScriptService.Playing.AlivePlayers.Value = game.Players.NumPlayers
            for i, v in pairs(game.Players:GetChildren())do
                local list = workspace.Spawns:GetChildren()
                m = list[math.random(#list)]
                v.Character.HumanoidRootPart.CFrame = CFrame.new(m.Position) + Vector3.new(0,5,0)
            end
            wait(2)
            game.ServerScriptService.CSScript.Disabled = false
            for i, v in pairs(game.Players:GetChildren())do

                v.PlayerGui.ScreenGui.ColorFrame.Visible = true
            end
            wait(121)
        end
        game.ServerScriptService.CSScript.Disabled = true
            for i, v in pairs(game.Players:GetChildren())do
                v.PlayerGui.ScreenGui.TextLabel.Visible = true
                v.PlayerGui.ScreenGui.ColorFrame.Visible = false
            end
            if game.ServerScriptService.Playing.AlivePlayers.Value > 1 then
                 text.Value = "Multiple people have won!"
            elseif game.ServerScriptService.Playing.AlivePlayers.Value == 1 then
                 text.Value = "One person has won!"
            end
            wait(5)
        game.ServerScriptService.Playing.AlivePlayers.Value = 0
        workspace.Map:ClearAllChildren()
end

is not working in the real game

Error: ScreenGui is not a valid member of PlayerGui

all of these scripts are in a regular script in ServerScriptService.
