How can I add two numbers with LineEdit and show the answer in label?

I am trying to make an app to add two numbers. I used LineEdits to put numbers and a label to show the answer. Unfortunately, something is wrong. Could anyone here help me?

Your _ready() is empty and none of your custom functions are triggered by anything based on what I can see. Also that extra indent on the highlighted line 16 could be removed.

edit: I suppose your signals might be triggering the functions if set up properly, but I can't be sure of that I mean.

Edit 2: Ok, so instead of using Str() you should use String() on line 19, and since you used the text entered signal from the LineEdits, after inputting/changing the text you need to hit enter too.

So heres my example:

extends HBoxContainer # used HBoxContainer as parent for the other nodes

var num1 = 0
var num2 = 0
var result = 0
onready var res = get_node("OutputLabel")

# note that I've opted to use the _text_changed signal
func _on_InputLine1_text_changed(new_text):
	num1 = int(new_text)
	

func _on_InputLine2_text_changed(new_text):
	num2 = int(new_text)
	

func _on_CalcButton_pressed():
	result = num1 + num2
	print(res.text)
	print(result)
	res.set_text(String("Result: ") + String(result))
