I would like to create a custom search form to search posts based on the values of about 4 custom fields. I tried using wp_query to achieve this but so far my biggest problem is that the I don't get any results when searching for data in custom fields - even for data that I am sure exists. Also, I can't figure out how to remove the normal WordPress "keyword" search box and use just my four combo boxes.
Here is the code from my search.php file: http://pastie.org/private/jhgsmaolvjyswyhsfphlfa
and here's the code from my searchform.php: pastie.org/private/o3hrtqajh8hbkiht1nyoba
