how to fix an if (variable condition) do script?

im pretty new to roblox scripting so sorry if it look at little messy but heres my script where i want a brick to set on fire and a bunch of other stuff if clicked too many times, everything works except the actions for when the script gets to a certain variable

CatAnger = 0

function onClick(click) 
    print(CatAnger)
    CatAnger = CatAnger + 1
end

script.Parent.MouseClick:connect(onClick)

while true do
    wait(0.5)
    CatAnger = CatAnger - 1
end

while true do
    if CatAnger > 5 then
        print("DO BEEP BEEP")
    end
    wait(1)
end

function angery()
    workspace.AngerWall.Fire.Enabled = true
    workspace.AngerWall.Smoke.Enabled = true
    workspace.AngerWall.HappytheCat.Transparency = 1
    workspace.AngerWall.angrycat.Transparency = 0
    workspace.AngerWall.AHHH.Sound:Play()

end

while true do

end
if CatAnger < 0 then
    print("1^")
    CatAnger = CatAnger + 1
end

this is the entire script and here are my problems

while true do
    if CatAnger > 5 then
        print("DO BEEP BEEP")
    end
    wait(1)
end

(designed to trigger a function when its over 5)

if CatAnger < 0 then
    print("1^")
    CatAnger = CatAnger + 1
end

(designed to put it back to 0 when it goes under 0)

i've tried to add while true do loops to always be checking if its over but no luck, i'm sure there's a simple answer, plz help C:
