When part touched, gui pops up and gui text color changes?

Context: I am making a horror game. There will be a task bar/mission thingie on the top right. When a player touches an invisible, cant collide part, the mission changes. It glitches and says something. then after a bit of "glitching" it turns back to normal.

Problem:

Well... I dont really know. I have triple checked every variable is correct (leads to the correct spot), and there are no errors in the script and in output. I tried putting "print("Done!")" at the ned, and the print doesn't print into output, which is proof is crewed up somewhere. Thanks in advance, any help is appreciated.

Script: links to images of my code and stuff: https://ibb.co/ZXrxmbB | https://ibb.co/xj5Jd87 | https://ibb.co/tqC6RdW | for the last image: on the top right it should not say "Go into the faculty room" and instead be glitchy and say "Go into the closet" before going back to normal

local screengui = game.StarterGui.Missions
local frame = screengui.Frame
local glitch1 = frame.Image
local glitch2 = glitch1.ImageLabel
local glitch3 = frame.ImageLabel
local glitch4 = glitch3.ImageLabel
local glitch5 = glitch4.ImageLabel
local all1 = glitch1 and glitch2
local all2 = glitch3 and glitch4 and glitch5
local all = all1 and all2
local changer = script.Parent
local colorgreen = Color3.new(0.113176, 0.655909, 0.0112764)
local colorred = Color3.new(0.985977, 0, 0.0269932)
local colorblack = Color3.new(0, 0, 0)
local colorblue = Color3.new(0, 0, 0.998184)
local colorwhite = Color3.new(1,1,1)
local debounce = false
local text = frame.Text
all.Visible = false
script.Parent.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") == true and debounce == false then
		debounce = true 
		text.TextColor3 = colorred
		text.Text = ("Go into the closet")
		wait(0.3)
		text.TextColor3 = colorgreen
		all1.Visible = true
		text.Text = ("g0 iNTo tHE clOSEt")
		wait(0.09)
		text.TextColor3 = colorblack
		all1.Visible = false
		all2.Visible = true
		wait(0.1)
		all2.Visible = false
		text.TextColor3 = colorwhite
		text.Text = ("GOINTOTHECLOSET")
		wait(0.5)
		text.TextColor3 = colorblack
		wait(0.2)
		text.TextColor3 = colorwhite
		all.Visible = true
		wait(0.13)
		all.Visible = false
		print("Done!")
	end
end)

put this at line 21:

if hit.Parent:FindFirstChild("Humanoid") and not debounce then

you're doing humanoid == true, which is incorrect. instead, use:

if hit.Parent:FindFirstChild("Humanoid") then

which means it checks if Humanoid exists, hopefully this helps! oh also, "not debounce" means "debounce == false", pretty much the same
