Textlabel not changing when the textbutton is activated?

So I'm trying to make some sort of dialog for my game. I'm trying to make a textbutton change the text of the textlabel.

local button = script.Parent
local main = game.StarterGui.ScreenGui.Frame.MainDIalogue.Text

local function onClicked()
	main = "something something"
	
end

button.Activated:Connect(onClicked)

However, when I try clicking on the textbutton. Literally nothing happens, no error, no change. Just nothing. Did I reference something wrong or probably I have it in the wrong order? Im using a local script for this by the way.

Is it meant to say "MainDIalougue" and not "MainDialougue", There is a capital i that i don't think should be there unless you added it on purpose. Its case sensitive.

I found the fix when i was testing, you have to make the variable not say text then add text onto the function

local button = script.Parent
local main = game.StarterGui.ScreenGui.Frame.MainDIalogue

local function onClicked()
	main.Text = "something something"
	
end

button.Activated:Connect(onClicked)
