Drupal 7 Theme [Business] not pulling in to non-front pages
If you want page specific theme'ing, look at themekey module:


  ThemeKey allows you to define simple or sophisticated theme-switching
  rules which allow automatic selection of a theme depending on current
  path, taxonomy terms, language, node-type, and many, many other
  properties. It can also be easily extended to support additional
  properties exposed by other modules.
