fml the guy was quicker because I was getting actual URLs for the guy to use...
Anyway, he did not explain it in a good way and I have already written this so:
http://www.plazmaburst2.com/level_edito ... lename=c0a for level 1.
it works like this, at the end of the URL, you have that c0a, "c" + you get the level you want-1 + "a", so level 1 is c0a, level 2 is c1a, level 20 is c19a, level 42 is c41a, etc.
