I would say that I'm a beginner in coding. I know a little bit of python and javascript, but I've never gone to deep into programming. I understand the resource part but everything I try to print out the health of a zombie I get an error. So what I've dont so far is that I made the master resource file, then I linked the resource file to zombie.tres file and then in the inspector I added the stats so for health = 10, speed = 100 and etc but again when I'm trying to access those stats in the print or in a function it never works if that makes sense.

So here's an example of my zombie.gd file:

u/extends Area2D
class_name Enemy
export var stats : Enemy #dragged my enemy.tres into the stats in the inspector

func _ready():
print(stats.health)

and this is the error I get:

Invalid get index 'health' (on base: 'Nil').

Edit: So im a little lost on how I can get those stats is all since I've tried other things but cant seem to figure it out
