I'm running Godot v 3.1.1. I've done some tutorials with v 2.x in the past, but just installed v 3.1.1 and already hitting a roadblock on something that should be pretty easy.
What I'm doing is pretty simple - just trying to connect the "pressed" signal to my Panel control object, but I get the error, "Target method not found! Specify a valid method or attach a script to target node".
var money = 0
$MoneyLabel.text = "$" + str(money)
Connect Signal dialog
Connect Signal error
