make a search box...

[Winterworks]

					<form action="index.php" method="post">
	<div class="search">

		<input name="searchword" id="mod_search_searchword" maxlength="20" alt="Search" class="inputbox" type="text" size="20" value="search..."  onblur="if(this.value=='') this.value='search...';" onfocus="if(this.value=='search...') this.value='';" />	</div>
	<input type="hidden" name="task"   value="search" />
	<input type="hidden" name="option" value="com_search" />
</form>		</div>

I have that code. That shows up as a search bar, but when you type something in it, and press enter, nothing happens, it just refreshes the homepage (probably because of the "form action="index.php"")

Currently you can type something, press enter, and it'll refresh the homepage. How can I make it search my forum, and come up with the vBulletin search results page?

How would I do this?

View the source code of a normal search box in vBulletin, and use that code. However, you must have the security token whenever you use the code, otherwise vBulletin will throw you an error.
