LEVELING SYSTEM HELP

I need help with my level system. I want to have when you reach the bar reach’s a specific amount (30) my label gets a plus 1. My label shows what level the player is. This is the game: http://flowlab.io/game/play/1376419

I have an example for you in this game. Search for the user interface object named “XP Display”. It should give you the basics on making a level system.
