Moving Search Form?

I’d like to bring it down right below the banner on the right. The blog is at fittedhawaii.com/updates/test.

This is the code in Header.php for the search form:

<div id="right-header">
<form method="get" action="<?php echo $_SERVER['PHP_SELF']; ?>" id="searchform">
<input name="s" type="text" class="intext" value="Search Keyword" onfocus="if (this.value == 'Search Keyword') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Search Keyword';}" size="10" tabindex="1" />
<input name="search" type="image" src="<?php bloginfo('template_directory'); ?>/images/search.png" alt="search" class="inbutton"/>
</form>
</div>

What do I need to change?
