After Ludovic C. solved my last problem
I have another problem relating to the numbering of subfigures.
When I reference a picture with the number (1) like this
I get Fig. 011 instead of Fig. 1. I guess it has something to do with the solution for my numbering of subfigures (see link above)!
Maybe it is Fig. "chapter""figure""subfigure", but I am not sure. And it would be great to know how to change it to just "subfigure"! This is my first time using Latex and I am trying my best to use google etc., but I cannot find a solution to this. It seems to be too unique of a problem.
Thank you very much for your efforts :)
