Script not working...help?

This is a speed pickup. Basically, it changes your maximum walkspeed by 34, but, it doesn't do anything. It just continues to float. Any ideas?

print'Script - Working'
local Pack = script.Parent
Pack.Handle.BodyPosition.position = Pack.Handle.Position
Pack.Handle.Anchored = false
Took = false
script.Parent.Handle.Touched:connect(function(hit)
    if hit.Parent then
        local Patient = hit.Parent:findFirstChild("Humanoid")
        if Patient then
            if Patient.Walkspeed then
                if not Took then
                    Took = true
                    Patient.Walkspeed = Patient.Walkspeed + 34
                    Pack.Parent = nil
                    wait(15)
                    Pack.Parent = Workspace
                    wait(1)
                    Took = false
                end
            end
        end
    end
end)
