let's see if images will help then...
Step 1: In your Wordpress Dashboard, go to the Pages tab and click Add New...just like how you added the About Us and Contact pages to your site.
Step 2: In your new Page, paste the code for the results box. Since it's code you are pasting in, make sure you are in the HTML tab (circled in red below) and not the Visual tab. Title/Name the page, then Publish it.
Step 3: In your Google custom search control panel, go to the section where you got the two separate code snippets. In the top section (highlighted in yellow below), type in the URL address of the new page for the search results...for example: http://www.www.smashinghub.com/find/
Notice that the URL is added to the search box code (in red box above) as you type it.
You will have to add or change that value in the search box code on your site (red text in the search box code below)...
<form action<font color='"Red"'>="http://www.www.smashinghub.com/find/"</font> id="cse-search-box">
<input type="hidden" name="cx" value="013723053986055911592:k-qc7jh47_g" />
<input type="hidden" name="cof" value="FORID:10" />
<input type="hidden" name="ie" value="UTF-8" />
<input type="text" name="q" size="31" />
<input type="submit" name="sa" value="Search" />
does that help clear anything up a little?
