SurfaceGui not working inside tool, how can I fix it?

So, I made a tool with a little SurfaceGui on, and it just doesn't want to work, I first of all know for a fact that the box highlights grey if a player hovers over it as I didn't change any properties, but then i set up a little script, which warns "BUTTON CLICKED!" if the button is clicked.

Here is the full code:

--[[
  ______  _____ _____  
 |  ____|/ ____|  __ \ 
 | |__  | (___ | |__) |
 |  __|  \___ \|  ___/ 
 | |____ ____) | |     
 |______|_____/|_|
