Frame won't show in renpy (Python)

Question

I am tryign to make a game in renpy, and i implemented a small rpg like mechanic, and i was trying to show healthbars. it was working for a bit, but then it stopped and i don't know why. I checked my variables and everything seemed to be in order. maybe someone here can help me out. Below is the small rpg screen setting segment.

label rpg_test:
play music "Boss_Fight.wav"
$ attack = 0
if "dagger" in inventory == True:
  $ player_attack + 2
$ kdragon_hp = kdragon_max_hp
define gui.bar_tile = True 
define getting_attacked = "No one"
$ kdragon_max_hp = 50 * len(party)
$ kdragon_hp = kdragon_max_hp

I tried to fill your screen with data and it worked fine. Check the variables you have, make sure you are showing or calling the screen, that's not in the piece of code you provided: call screen simple_stats_screen or show screen simple_stats_screen.
