What is wrong with this script? Changing the different things in a model when touched by a tool

I am trying to make a coffee system, meaning that I get coffee beans from the machine, then go to the pot and put the beans in, then I can get a cup and touch the pot to put coffee in it.

I'm at the stage of putting beans into the pot however I don't know what is wrong with this script.

local part = script.Parent
local function fillcup(CoffeeBeans)
    if CoffeeBeans.Filled.Value == false then -- This value is because the code was intended for filling cups
        CoffeeBeans.Filled.Value = true
        CoffeeBeans:Destroy()
        script.Parent.Coffee.Color = BrickColor.new('Dirt brown') - Changes the color of the water to the color of coffee
        script.Parent.Colour.Red.Disabled = false
        script.Parent.Colour.Orange.Disabled = false
        script.Parent.Colour.Yellow.Disabled = false
        script.Parent.Colour.Green.Disabled = false
        script.Parent.Colour.Blue.Disabled = false
        script.Parent.Colour.Purple.Disabled = false --[[ 
I have different color cups each with a different script to fill them, that script so far has been working
]]--    
    end
end
part.Touched:Connect(function(parttouching)
    if game:GetService("Players"):GetPlayerFromCharacter(parttouching.Parent) then 
        if parttouching.Parent:FindFirstChild("CoffeeBeans") then 
            fillcup(parttouching.Parent.CoffeeBeans) 
        end
    end
end)

The code was originally intended for filling cups and I also got the code from someone else.

To specify what game I'm making, I am making a recreation of the town (Stars Hollow) from a TV show called Gilmore Girls and I'm trying to make it interactive. I also only have a very basic understanding of scripting.
