Implementing Trip_Search into my theme

I replaced the core search function in my drupal installation with the trip_search module I love the features it has but I am having difficulty printing the search block into my theme.

So I tried replacing $search_box with $trip_search_block and that didn't work.

I don't know if it is associated but currently the search box is only showing up if I'm logged in as a administrator.
