i´m in trouble because it doest´t work when i change parts of my masterpage of my theme. I tried to edit dndindex according to this tutorial http://docs.oxwall.org/design:how-to-create-customize-themes-for-beginners .

however, when i implement such a "box" nothing changes at all. I`ve checked the source-code in my browser and nothing that I have changed appeares there. I dont know what I've done wrong. 

May somebody help me?

Thanks a lot!
