In the levelButton class, change "ButtonImage" in line 31 to "levelImage".

thank you sorry i didn't respond till so late, but is there any way you can think of so that a new button appears when level one is beaten, level 2, act…, however if you replay an earlier level it doesn't remove the new one? I'm sorry for coming to you for all my issues.

I think the problem is that the level counter is always initially one every time you create a new Levels object. I do not think it to be a very simple fix. Maybe you should take a look at my Super Level Support Class Demo scenario. It might lead you in the right direction.
