Why is the mousebutton1click not working?

This is my code:

script.Parent.MouseButton1Click:Connect(function()
	print("E")
end

The code is in a textbutton and the textbutton/gui is in a playergui which was cloned from the tool when equipped.

Whenever I try to click the button nothing happens. I checked my output and there is nothing.

Why is nothing happening?

Your script actually does work but, you forgot the extra parenthesis behind "end"

Also make sure you run it with a Local script

Here's the fixed script:

script.Parent.MouseButton1Click:Connect(function()
    print("E")
end)
