Everything worked fine until I added the body data-spy="scroll" data-target=".subnav" data-offset="80"

the scrollspy to activate the links on my nav-pills is not working, I must have went wrong somewhere. I can get the script to make it scroll bellow my top-nav just fine but when I put the modded body tag in it stops scrolling as well and just becomes static. Any idea of what I have done?

jQuery, plus either bootstrap.js or bootstrap-scrollspy.js are required. Have you included those before this script?

@ithertz

All are included, I am however using jquery 1.8. I'm pretty sure I've seen this feature working without a problem in 1.8, and they are located before the script above.

without the additions to the body tag, the subnav works fine, readjusts to the page and scrolls down with the top-nav. but for some reason the second it gets that addition to telling it to data-target the subnav it breaks and goes static.

Edit: just recently realized the scroll-spy is in fact working after it scrolls off the page, so somehow one script is overwriting the other when they are both present.

Problem solved, I had messed something up in the Javascript file itself that you provided, thanks for the help

I just updated the JS code to get rid of content "jumps" when subnav changes to subnav-fixed.
