Problem/Bug BedWars Reloaded Shop not working

hi guys i recently downloaded bedwars reloaded and i wanted to customise my shop, i changed the values so that instead of bronze iron and gold i used iron gold and emeralds and i made a shop, but when i start the game, it wont let me access the shop, here is the code

Code:

# amount: 1
# meta:
