Touched is not a valid member of Workspace?

Im Trying to make a game called Boulder Run Where you run from a boulder and i want to make a message saying who has survived the boulder by touching this invisible brick

h = Instance.new("Hint", game.Workspace)

local db = false
function onTouched(hit)
    if hit.Parent == nil then Print ("gun") return end
    if db then return end
    db = true
    local pName = game.Players:GetPlayerFromCharacter(hit.Parent)
    print(pName)
    h.Text = pName 
    wait(5)
    msg:remove()
    db = false

end

script.Parent.Touched:connect(onTouched)
