I am a bit new, but I hope my problem is not to trivial

My problem is that numbering of figures and listing is going 1, 2, 3, ......
I would like them to go 1.1, 1.2, 1.3 for chapter 1 and 2.1, 2.2, 2.3 for chapter 2 etc.
How is it possible to do this trick? I am using bibtex for setting up my latex document. If you need to look at it, I attached it here.
I hope you can help me finding a solution, because I am still lost after searching the internet.
