Hello,

I want to have a float called figuren with this properties.

1. figuren numbering shall not interfere with figure numbering.
2. figuren numbering shall restart each chapter.
3. have this caption:

   figure exer 1-1: This is a caption text ...

But I get an error.

Code: Select all

! LaTeX Error: No counter 'subfiguren' defined.

this is my file:

Please read the subfig documentation, especially "4. Compatibility With Other Packages." / "4.2 Float Package".

There you'll find an example code for creating new types of sub-floats.
