Ads on all pages

Hey

I’ve been wanting to put an ad under my navigation bar on my site for some time. I finally got around to it today, and placed the code inside the index.php right after the get header. The only problem with this is that I find that it only displays ads on the home page. I want them on all pages, including blog posts, search results, pages, etc. How would I go about doing that? Thanks

EDIT- Nevermind, I figured it out.
