how do I simply change a surface gui text on a brick with a script?

I'm actually pretty surprised of this issue. It would seem so simple but it just doesn't work, no errors either.

local text = script.Parent.Text

text = ('hello')

Reference vs Value

when doing something like

local text = script.Parent.Text

it is essentially setting a variable equivalent to the text of the object, rather than actually being tied to the text of the object.

For that, you would do something like this:

local thing = script.Parent

thing.Text = "hello"

ik this goes without saying but, if this is a surface gui on the server, be sure to use a server script

Hopefully this helped!
