ALRIGHT I got it for work!
What I did was change the following ...
<div class="bs-docs-sidebar span3"> <ul class="nav nav-list bs-docs-sidenav affix-top">
For...
<div class="bs-docs-sidebar span3"> <ul class="nav nav-list bs-docs-sidenav affix" data-spy="affix" data-offset-top="255" data-offset-bottom="200">
So, I put the data spy and data offset into the "bs-docs-sidenav" class, changed the script to this class, and not to the "bs-docs-sidebar" class.
Then I edited the css "affix-top", "affix" and "affix-bottom" and it works fine :)
My original problem was with the sidebar class instead of the sidenav class, because that is what my CSS affix worked on.
Hope this helps anyone who had the same problem, mine :)
What helped me with this, these tutorials .
