Is this blender script correct? Need help with this script.

I would like to make item givers and stuff like in many cafe typed games. I can make item givers but I would like to make a Blender, something like;

Cup(item) -> Ice machine -> Blender.

I want the blender to take sometime and change the colour. This script doesn't work. How do I fix this.

function tch(h)
if (h.Parent.Name == "Anything") then -- Same thing ^^^^
h.Parent.Name = "Blending..." -- Not this one.
script.Parent.Sound:Play()
script.Parent.Parent.Part1.BrickColor = h.Parent.Handle.BrickColor
script.Parent.Parent.Part2.BrickColor = h.Parent.Handle.BrickColor
script.Parent.Parent.Part3.BrickColor = h.Parent.Handle.BrickColor
script.Parent.Parent.Part4.BrickColor = h.Parent.Handle.BrickColor
script.Parent.Parent.Part5.BrickColor = h.Parent.Handle.BrickColor
script.Parent.Parent.Part6.BrickColor = h.Parent.Handle.BrickColor
script.Parent.Parent.Part7.BrickColor = h.Parent.Handle.BrickColor
script.Parent.Parent.Part8.BrickColor = h.Parent.Handle.BrickColor
script.Parent.Parent.Part9.BrickColor = h.Parent.Handle.BrickColor
wait(0.1)
script.Parent.Parent.Part8.Transparency = 0
script.Parent.Parent.Part9.Transparency = 1

wait(0.1)
script.Parent.Parent.Part9.Transparency = 1
h.Parent.Name = "Change to anything!" -- Anything
wait(0.5)
end
end

script.Parent.Touched:connect(tch)

Once I insert the cup or whatever, it's stuck at "blending" and wouldn't show any music or stuff... Please help.

Thank you.

Simply add a debounce to lines 1,3 and 73:

Line 1:

bool = true

Line 3:

bool = false

Line 73:

bool = true

Because there is no debounce in your script, the function will continue to run as long as it is continuously called. Debounce stops the function after running once.
