QuailFire theme dedicated search bar wont search products.

Hey guys, Im using the QuailFire theme to make a online computer store for my business. At this stage im running it on a addon domain from my personal website so when its done i can transfer it.
The problem im having is with the search engine on the top right corner of the page (Theme dedicated)
Ive put a few test products in the store to play around with and ive noticed that the search engine wont pick up anything in the search results. Ive tried looking at the scripts but i dont think there is an issue there, IM not all that smart about coding anyway so i could be wrong. if someone could tell me whats wrong with it or if someone could give me a script to use instead of the dedicated one i would be very happy. Although i like the look of the one thats there now, if you think its a better script please post it for me. here is the script im using now.

<div id="search" class="grid_7 prefix_17">
		    <form action="<?php bloginfo('wpurl'); ?>/" method="get">
			<div class="search_box">
			    <input id="search_field" name="s" type="text" class="inputbox_focus inputbox pngfix" value="<?php esc_attr_e('Search...', 'qualifire'); ?>" />
			    <input type="submit"  value="" class="search-btn pngfix" />
			</div>
		    </form>
		</div><!-- end search -->

my website url is: ptnetworx.petrutiglar.com

Thanks guys!
