How do I use the _self tag with my search engine?

[Maverick]

I've got a search engine on my site. When I press the submit button it opens the page in a new window whereas I want it to open over the top of the old page. I can do this by putting a base target _self tag into the header but this affects my whole site. Any ideas anyone?

Here's part of the code in case that helps...

<form method="get" action="http://search.atomz.com/search/">
<input size=25 name="sp-q">
<input type=submit value="Search" name="submit">

<form method="get" action="http://search.atomz.com/search/" target="_self">

Thanks, that worked perfectly. I didn't expect it to be that simple :)
