Why won't my textbutton do anything onclick? [SOLVED]

**THANKS SO MUCH iiiAmericanLight FOR SOLVING THE QUESTION! ** So, I'm making a game, obviously, and I'm trying to make these imagelabels turn visible by the press of a button, but the button doesn't do anything. Before you ask, the imagelabels work perfectly if I manually turn them visible on Roblox studio, it's just I want it where, like I said, the button turns them visible. When I mean they work perfectly, I mean that they turn visible. The script:

local Cat = script.Parent.Parent.Cat
local Cat2 = script.Parent.Parent.Cat2
local Cat3 = script.Parent.Parent.Cat3
local Cat4 = script.Parent.Parent.Cat4
local Cat5 = script.Parent.Parent.Cat5

script.Parent.MouseButton1Click:connect(function()
    script.Parent.Text = "Hi"
    Cat.Visible = false
    Cat2.Visible = true
    wait(0.2)
    Cat2.Visible = false
    Cat3.Visible = true
    wait(0.2)
    Cat4.Visible = true
    Cat3.Visible = false
    wait(0.2)
    Cat4.Visible = false
    Cat5.Visible = true
    wait(0.2)
    Cat5.Visible = false
    Cat4.Visible = true
    wait(0.1)
    Cat4.Visible = false
    Cat.Visible = true

end)

Thank you!
