Why does my goal script error saying "unexpected symbol"?

I'm trying to create a goal in ROBLOX:

db = false -- We make this variable, so that we can make sure Bright red Team doesn't instantly make Bright blue Team lose more than 1 point by just 1 Kick Off.

script.Parent.Touched:connect(function(hit) -- When the script's parent (BlueGoal) is touched
if hit and hit.Name == "Ball" and db == false then -- We need to know if the debounce is off, and if the part that touched BlueGoal is named 'Ball'
db = true -- Turn debounce on, so that for the next 3 seconds we can't lose more than 1 point.
message = Instance.new("Hint").Parent = Workspace -- Add a new Hint to the Workspace so that we know what's going on.
message.Text = "Bright blue Team loses 1 point! Kick Off!" -- Set the Hint's Text accordingly and display the message.
wait(3) -- We wait 3 seconds to make sure everyone can read the message.
message:destroy() -- We hide the message by :destroy()ing it.
db = false -- We turn debounce off again so that we can score more points.
end
end)

The problem is, it errors. :( Workspace.BlueGoal.Script:6: unexpected symbol near '='

Please help.
