Need some help here

I'm trying to get the indestructable cheat to work so my 4 year old daughter can play the game. I made the change on the flux.ini file. I also added the cheats to the default.ini file. I can get the damage yourself cheat to work but the other ones don't. I double checked my spelling and it's not that either. Does anybody have any advice? Thanks.

greetings to your daughter:D
but don't let her drive your car...

flux.ini: developer_mode = 1 ?
use maindirectory/configs/default for cheats ?

I figured out the problem. I had a semi-colon in front of the indestructable cheat. The game thought that it was just a comment instead of actuall code. Well now I can introduce my daughter to the game!
