Global_Postioning Troubles while trying to make a Mario Question Mark block

Hi!

First time poster, I'm a novice looking for some help with the use of global_positioning troubles. I've been following various youtube guides to build a Mario clone for fun and am trying to add a Mario style question mark block to my game that may be bumped in to to produce a power up item. I've been using the youtube channel, AJ's Learning Labs - Question Mark Blocks tutorial and am trying to bash his lesson into what I had already built. The tutorial runs functions across two scripts and then pulls in an item with a third script. However when added to my game it gets hung up on pulling the global_postion of the item i wish to be produced from the block.

The Stack Trace log error is:
Invalid set index 'global_position' (on base: 'CharacterBody2d (Bottoms.gd)') with value of type 'Vextor2'

Stack Frames being flagged are:
global.gd:6 - at function: spawn_bottoms
p_block.gd21 - at function bump_block
p_block.gd14 - at function _on_body_entered

My 3 scripts are:

global.gd <-- This script is setup to autoload in the project settings.

extends Node

func spawn_bottoms(pos):
	var BottomsScene = load("res://World Objects/bottoms.tscn")
	var Bottoms = BottomsScene.instantiate()
	Bottoms.global_postion = pos
	get_tree().root.add_child(Bottoms)

p_block.gd <-- script for the block | Enter Body node connected on "func _on_body_entered" line 12

extends Area2D


enum State { UNBUMPED, BUMPED }
var state: int = State.UNBUMPED
var original_position: Vector2

func _ready():
	original_position = position
	

func _on_body_entered(body):
	if body.is_in_group("Player") and state == State.UNBUMPED:
		bump_block()
		
		
#Logic for bumping the block
func bump_block():
	state = State.BUMPED
	$Sprite2D.frame = 1
	Global.spawn_bottoms(self.global_position + Vector2(0, -20))
	bump_upwards()
	var timer = get_tree().create_timer(0.2)
	await timer.timeout
	return_to_original_position()
	
	
	
#Function to move the block upwards
func bump_upwards():
	position.y -= 10 # move up 10 units
	
#Function to return block to original position
func return_to_original_position():
	position = original_position

Bottoms.gd <-- script for item being produce by the block | Enter Body node connected on "func _on_area_2d_body_entered" line 12

extends CharacterBody2D

var speed = 30
var direction = 1 
var gravity = ProjectSettings.get_setting("physics/2d/default_gravity")

func _physics_process(delta):
	move_and_slide()
	velocity.y += gravity * delta
	velocity.x = speed
	
func _on_area_2d_body_entered(body):
	if body.is_in_group("Player"):
			queue_free()
	else:
			direction *= -1

The game will crash when my character (it is grouped as "Player") jumps up and bumps into the block. If I trace the log back it looks like the issue stems from this line of code in global.gd:

Bottoms.global_postion = pos
But at this point i'm ignorant as to what to do next.
May I please have some help on how to solve this or best proceed
Thanks!!
