Gamemode Selection Doesn't work properly?

I'm trying to make a gamemode selection, I use an Int Value and I did that if the value is 0 it makes the text say Solo, If it's 1 it makes it say Duo (Team of 2). The problem is that when I press the previous gamemode button and it says solo it doesn't do anything, But if it says Duo it makes it say Solo but I want it to when it says Solo and I press it, The text says Duo (Team of 2).

This is my first script:

local Gamemode = script.Parent
local Next = Gamemode.NextGamemode
local Previous = Gamemode.PreviousGamemode
local GamemodeValue = Gamemode.GamemodeValue

Next.MouseButton1Click:connect(function()
	GamemodeValue.Value = GamemodeValue.Value + 1
end)

Previous.MouseButton1Click:connect(function()
	if GamemodeValue.Value == 0 then
		GamemodeValue.Value = 1
	end
	
	if GamemodeValue.Value == 1 then
		GamemodeValue.Value = 0
	end
end)

This is my second script:

local ChosenGamemode = script.Parent.Parent.ChosenGamemode

while true do
	wait(0.01)
	
	-- Gamemode Limit
	
	if script.Parent.Value == 2 then
		script.Parent.Value = 0
	end
	
	--  Gamemode Text
	
	if script.Parent.Value == 0 then
		ChosenGamemode.Text = "Solo"
	end
	
	if script.Parent.Value == 1 then
		ChosenGamemode.Text = "Duo (Teams of 2)"
	end
end

Btw, This script is inside the Int Value.

Thanks, MajinBluee

First of all, you should use the .Changed event to detect when the value changes, rather than a consant loop. You should also use elseif for cleaner code.

script.Parent.Changed:Connect(function(NewVal)
	if NewVal > 1 then
		script.Parent.Value = 0
		NewVal = 0
	end
	local Text = ChosenGamemode.Text
	if NewVal == 0 then
		Text = "Solo"
	elseif NewVal == 1 then
		Text = "Duo (Teams of 2)"
	end
	ChosenGamemode.Text = Text
end)
