Multiple Drop Down Select Options

[Kurius]

Hi, I was given this code from a friend I'm trying to help but I'm stuck. The original code had two drop down options for type and year. I've added a third option for skill. How can I get PHP to run through this drop down on submit.

This is the original http://codepad.org/hK2lJbbt and this is my new one with added options http://codepad.org/MW66Ro2M

I tried adding a new elseif statement after the WP_query but It's not sorting

elseif(!empty($_POST['author-skill']) && !empty($_POST['author-type'])){
    if($yr != $_POST['author-skill'] || $author_type != $_POST['author-type']) continue;
}

Messed up the elseif statement I am using, still not sorting though.

elseif(!empty($_POST['author-skill']) && !empty($_POST['author-type'])){
    if($yr != $_POST['author-yr'] || $author_type != $_POST['author-type']) continue;
}

"not sorting" ? Can you be more clear about what your problem is?
