I'm new to the site and to web development in general. I have a domain name, a hosting site, and wordpress installed. That took me most of a day. Now I'm trying to add this functionality to my site http://www.9lessons.info/2010/09/youtube-instant-search-with-jquery-and.html as a proof of concept before heavily modifying it.
The problem is that while I can paste that code into an HTML file and run it perfectly, I can't get my wordpress site to fire it off within a page no matter what I try. After spending a good 6 hours banging my head around with things like child templates, the function.php file, etc. etc. I still can't get it working. What am I missing?
