Thanks again, you are a true hero
I do have a problem though (surprise, surprise!). At the end of the layout, 1 is added to LevelProgress and the next level is unlocked.
LevelProgress = 1 = Unlock Level2
LevelProgress = 2 = Unlock Level3
The problem is if you play the first level twice, you'll also get LevelProgress = 2 and then the third level is unlocked.
