If you want the y-axis or other to be anything, what should you do?

local PartColor = game.Workspace.MixingMachine.RedPipe.ColorEnergy
local Part = game.Workspace.MixingMachine.RedPipe
local button = script.Parent
local posi2 = 0.5
local NumOperate = 1

button.MouseButton1Up:Connect(function()
    if NumOperate == 1 then
        while true do
            if posi2 > (bla,-14.412,bla) then
                PartColor.CFrame = PartColor.CFrame * CFrame.new(-posi2,0,0)
            end
        end
    end
    if NumOperate == 2 then
        while true do
            if posi2 > (bla,11.588,bla) then
                PartColor.CFrame = PartColor.CFrame * CFrame.new(posi2,0,0)
            end
        end
    end
end)

I don't know how to do that. can you help me? if you can.
