Secondary Pages Dont Recognize Custom Theme

We are playing aronud with this theme and find it really powerful and easy to work with, but cannot figure out why our custom webfont won’t work on secondary pages. We are using Mohave for our headlines, and it works great on our front page, but headlines revert to open sans condensed on all other pages.

We included:
<link rel="stylesheet" href="mohave/stylesheet.css"> in our header and loaded the webfont files (generated using fontsquirrel). That part is working perfectly because it is showing on the front page.

Our only idea was that there was something in your functions for calling the different header on the front page, but we couldn’t figure out where that could be fixed. Also, we don’t think that’s the issue because we call the Open Sans Condensed google font in the same spot and that’s the font the pages are reverting to.

All other pages and blog pages.

and http://5giants.com/search-engine-optimization/ to see the examples.

Please let me know if you have any ideas. We really want to use this theme for our project.

Thanks!
