Question regarding search page form

I just have a small question regarding my searchform.php file below:

<div class="searchform">
<?php $search_text = "Search the website"; ?>
<form method="get" class="searchform" action="<?php bloginfo('home'); ?>/">
<input type="text" value="<?php echo $search_text; ?>" name="s" id="s"
onblur="if (this.value == '')
{this.value = '<?php echo $search_text; ?>';}"
onfocus="if (this.value == '<?php echo $search_text; ?>')
{this.value = '';}" />
<input type="submit" id="searchsubmit" value="Search" />
</form>
</div>

The $search_text string seems to only work with the onblur and onfocus when the text is longer than two words. I just want Search website. Is this possible?
