What I want to happen is when you click a button, it sets the text of a RichTextLabel and makes it visible. Here is my code:

extends TextureButton

# member variables here, example:
# var a=2
# var b="textvar"

func _ready():
	set_process(true)

func _input(event):
	if(Input.is_mouse_button_pressed(BUTTON_LEFT)): _flumpterado()


func _on_CarCheck_toggled( pressed ):
	get_parent().get_parent().get_node("KinematicBody2D").get_node("AnimatedSprite").get_node("CheckPanel").get_node("CheckText").set_bbcode("My car. Nothing more, nothing less.")
	get_parent().get_parent().get_node("KinematicBody2D").get_node("AnimatedSprite").get_node("CheckPanel").get_node("CheckText").show()

func _on_CarCheck_pressed():
	get_parent().get_parent().get_node("KinematicBody2D").get_node("AnimatedSprite").get_node("CheckPanel").get_node("CheckText").set_bbcode("My car. Nothing more, nothing less.")
	get_parent().get_parent().get_node("KinematicBody2D").get_node("AnimatedSprite").get_node("CheckPanel").get_node("CheckText").show()
func _flumpterado():
	get_parent().get_parent().get_node("KinematicBody2D").get_node("AnimatedSprite").get_node("CheckPanel").get_node("CheckText").set_bbcode("My car. Nothing more, nothing less.")
	get_parent().get_parent().get_node("KinematicBody2D").get_node("AnimatedSprite").get_node("CheckPanel").get_node("CheckText").show()

But the problem is: When I click the button, nothing happens. I don’t know if the RichTextLabel is not becoming visible for some reason, or if the button is not acknowledging the click, or what. But I need help solving it.

Edited to make the code more readable (hint: you have to add 4 spaces before each lines for the code to appear formatted).

Did you connected the pressed signal from the button to your function? Writing the function is not enough to make it detected.
Also, if you want to use _input(), you have to enable it by calling set_process_input(true).

I also strongly recommend you to put the RichTextLabel you want to set in a variable, so your code will be a lot more readable and efficient:

extends TextureButton


onready var richtext = get_parent().get_parent().get_node("KinematicBody2D/AnimatedSprite/CheckPanel/CheckText")


func _ready():
	set_process_input(true)


func _input(event):
	if(Input.is_mouse_button_pressed(BUTTON_LEFT)):
		_flumpterado()


func _on_CarCheck_toggled( pressed ):
	richtext.set_bbcode("My car. Nothing more, nothing less.")
	richtext.show()


func _on_CarCheck_pressed():
	richtext.set_bbcode("My car. Nothing more, nothing less.")
	richtext.show()


func _flumpterado():
	richtext.set_bbcode("My car. Nothing more, nothing less.")
	richtext.show()
