Busy with modifying the search functionalities.

Still this code here generated an error:
<form method="get" action="<$MTCGIPath$><$MTSearchScript$>">
<input type="hidden" name="Template" value="aroundmyroom">
<input type="hidden" name="IncludeBlogs" value="<$MTBlogID$>" />
<input id="search" name="search" size="24" class="search" value="Search AroundMyRoom" onfocus="clearDefaultValue(this) /><center><input type="" value=""" class="search" />
</center>
</form>

I want to have a search form without a button as it is now; but without the error ;-) Anyone?
