Was typing a code in a TextButton. But what the?

I was revamping my magic spell GUI but it worked, and I was using RemoteEvent (this is not the problem) then it worked, I pressed 1 and it worked but when I right click or left click my mouse it deactivates, the bad news is I want to keep the spells deactivates when a different number is pressed so the player won't spam all the spells at once. And the really bad thing I hate, you know, deactivates if it is used.

local players = game:GetService("Players").LocalPlayer or game:GetService("Players").PlayerAdded:Wait()

local character = players.Character or players.CharacterAdded:Wait()

local u = game:GetService("UserInputService")

local t = game:GetService("TweenService")

local mouse = players:GetMouse()

local againer = false

local image = script.Parent.Image

local cooldown = false

local mana = script.Parent.Parent.Parent.Frame.Bar.TextLabel.Mana

u.InputBegan:Connect(function(key)

if key.KeyCode == Enum.KeyCode.Two and againer == false then

image.Image = "rbxgameasset://Images/Pain Symbol"

againer = true

else

image.Image = "rbxgameasset://Images/dash"

againer = false

end

end)

script.Parent.MouseButton1Click:Connect(function()

if againer == false then

image.Image = "rbxgameasset://Images/Pain Symbol"

againer = true

else

image.Image = "rbxgameasset://Images/dash"

againer = false

end

end)

mouse.Button1Down:Connect(function()

if againer == true then

if mana.Value >= 100 and cooldown == false then

cooldown = true

script.Parent.Cooldown.Visible = true

script.Parent.Cooldown.Text = "4"

wait(1)

script.Parent.Cooldown.Visible = true

script.Parent.Cooldown.Text = "3"

wait(1)

script.Parent.Cooldown.Visible = true

script.Parent.Cooldown.Text = "2"

wait(1)

script.Parent.Cooldown.Visible = true

script.Parent.Cooldown.Text = "1"

cooldown = false

wait(1)

script.Parent.Cooldown.Visible = false

end

end

end)

script.Parent.MouseEnter:Connect(function()

script.Parent.INFO.Visible = true

end)

script.Parent.MouseLeave:Connect(function()

script.Parent.INFO.Visible = false

end)

If you don't get what I mean, this is the example: Player used a spell and left/right clicked and the spell deactivated, but Player wants the spell be activated almost all the time to spam it. But every clicks = spell deactivates, why?
