Why does my Overhead Gui not function as intended?

So the only one that would work would be 0, because there is no limiting. lets say i want to show a shade on someone's screen depending if their health is low enough, like in between 50 and 40 then it would get darker if it went to 40 to 30. I would have to write something like this:

local humanoid = game:GetService("Players").LocalPlayer.Character.Humanoid

humanoid.HealthChanged:Connect(function(health) 
    if humanoid.Health  <= 100 and 61 then -- this checks if the health is either 100 or higher then 61
        script.Parent.ImageTransparency = 1
    elseif humanoid.Health < 60 and  50 then -- the and in this checks if its higher then 50 but lower then 60.
        script.Parent.ImageTransparency = 0.9
    elseif humanoid.Health < 50 and 40 then
        script.Parent.ImageTransparency = 0.8
    elseif humanoid.Health < 40 and 30 then        -- Remember, this is a example.
        script.Parent.ImageTransparency = 0.6
    elseif humanoid.Health < 30 and 20 then
        script.Parent.ImageTransparency = 0.4
    elseif humanoid.Health < 20 and 5 then
        script.Parent.ImageTransparency = 0.3
    end
end)

the and inside the code is like the thing that limits it.

This code below should work the way you want it.

local TitleGUI = game:GetService("ServerStorage"):WaitForChild("Title")
02  game.Players.PlayerAdded:Connect(function(player)
03      player.CharacterAdded:Connect(function(character)
04          local titleguiclone = TitleGUI:Clone()
05          local Wins = player.leaderstats.Wins
06          if Wins.Value <= 4 and 0 then -- makes it only put the tag on there 
07              titleguiclone.Parent = game.Workspace:WaitForChild(player.Name).Head
08              wait(2)
09              titleguiclone.TextLabel.Text = "Noob"
10          elseif Wins.Value <= 9 and 5 then
11              titleguiclone.Parent = game.Workspace:WaitForChild(player.Name).Head
12              wait(2)
13              titleguiclone.TextLabel.Text = "Beginner"
14          elseif Wins.Value <= 14 and 10 then
15              titleguiclone.Parent = game.Workspace:WaitForChild(player.Name).Head
16              wait(2)
17              titleguiclone.TextLabel.Text = "Decent"
18          elseif Wins.Value <= 29 and 15 then
19              titleguiclone.Parent = game.Workspace:WaitForChild(player.Name).Head
20              wait(2)
21              titleguiclone.TextLabel.Text = "Very Decent"
22          elseif Wins.Value <= 44 and 30 then
23              titleguiclone.Parent = game.Workspace:WaitForChild(player.Name).Head
24              wait(2)
25              titleguiclone.TextLabel.Text = "Above Average"
26          elseif Wins.Value <= 59 and 45 then
27              titleguiclone.Parent = game.Workspace:WaitForChild(player.Name).Head
28              wait(2)
29              titleguiclone.TextLabel.Text = "Gamer"
30          elseif Wins.Value <= 74 and 60 then
31              titleguiclone.Parent = game.Workspace:WaitForChild(player.Name).Head
32              wait(2)
33              titleguiclone.TextLabel.Text = "Pro"
34          elseif Wins.Value <= 99 and 75 then
35              titleguiclone.Parent = game.Workspace:WaitForChild(player.Name).Head
36              wait(2)
37              titleguiclone.TextLabel.Text = "Amazing"
38          elseif Wins.Value <= 114 and 100 then
39              titleguiclone.Parent = game.Workspace:WaitForChild(player.Name).Head
40              wait(2)
41              titleguiclone.TextLabel.Text = "Awesome"
42          elseif Wins.Value <= 149 and 115 then
43              titleguiclone.Parent = game.Workspace:WaitForChild(player.Name).Head
44              wait(2)
45              titleguiclone.TextLabel.Text = "Ultra"
46          elseif Wins.Value <= 199 and 150 then
47              titleguiclone.Parent = game.Workspace:WaitForChild(player.Name).Head
48              wait(2)
49              titleguiclone.TextLabel.Text = "Chad"
50          elseif Wins.Value <= 100000 and 200 then
51              titleguiclone.Parent = game.Workspace:WaitForChild(player.Name)
52              wait(2)
53              titleguiclone.TextLabel.Text = "The One"
54          end
55      end)
56  end)

I hope this resolved your problem. Have a good day! - Zeta
