Can someone tell me what is wrong with my script?

Can someone tell me what's wrong. I'm new so I'm not really good at scripting. The onlything wrong is the word hint. I'll highlight it. disasters = {"Flying Noobs", "Explosive Noobs","Meteors","Giant Noob","Rising Lava","Jason","Slender Man","Giant Snowman","Illumina","Tsunami","Crazy Robloxian","Bomber","Rising Acid","Acid Rain","Raining Shurikens"} -- Disaster names are case-sensitive and all disaster models must be in the lighting

countdownTime = 10 -- Time between disasters. disasterTime = 5 -- The ammount of time that the disaster will be in the game before it is removed.

countdownMessage = "Next disaster in 60s seconds!" -- The message displayed between disasters. %s will be replaced with the number of seconds left. disasterMessage = "Disaster: nil" -- The message displayed when a disaster occurs. %s will be replaced with the disaster name. Set to nil if you do not want a message

-- Unless you know what you are doing, please leave the below code alone. items = {} leaderboard = game.Workspace:findFirstChild("BTS Leaderboard") -- Dont need to use with Ajedi´s BTS leaderboard, but if you want... local w = game.Workspace:getChildren() for i=1,#w do if w[i].Name == "leaderboard" and w[i]:findFirstChild("running") ~= nil and w[i]:findFirstChild("points") ~= nil then leaderboard = w[i] end end for i=1,#disasters do local item = game.Lighting:findFirstChild(disasters[i]) if item ~= nil then item.Parent = nil table.insert(items, item) else print("Error! ", disasters[i], " was not found!") end end

function chooseDisaster() return items[math.random(#items)] end

function sethint(text) local hint = game.Workspace:findFirstChild("hint") if (hint ~= nil) then hint.Text = text else print("Hint does not exist, creating...") hint = Instance.new("Hint") hint.Name = "hint" hint.Text = text hint.Parent = game.Workspace end --print("Hint set to: ", text) end

function removeHint() ** hint**= game.Workspace:findFirstChild("hint") if (hint ~= nil) then hint:remove() else
end end print("hint")

function countdown(time) sethint(string.format(countdownMessage, tostring(time))) while (time > 0) do wait(1) time = time - 1 sethint(string.format(countdownMessage, tostring(time))) end removeHint() return true end

while true do countdown(countdownTime)

if leaderboard ~= nil and leaderboard:findFirstChild("running") and leaderboard:findFirstChild("points") then 
    leaderboard.points.Value = 30
    leaderboard.running.Value = true
end

local m = chooseDisaster():clone()

if disasterMessage ~= nil then
    local msg = Instance.new("Message")
    msg.Name = "DisasterMsg"
    msg.Text = string.format(disasterMessage, m.Name)
    msg.Parent = game.Workspace
    wait(3)
    msg.Parent = nil
end

m.Parent = game.Workspace
m:makeJoints()
wait(disasterTime)
m:remove()

if leaderboard ~= nil then  
    leaderboard.running.Value = false
end

end
