 * Forgive me for my ignorance, but Ive been annoying people all over the web trying
   to figure out how to keep my search function dynamic once I use WP Cache on my
   site.
 * This was the code I was using to run my search function prior to installing wpcache:
 * <form style="padding: 0px; margin-top: 0px; margin-bottom: 0px;"
    id="searchform"
   method="get" action="<?php bloginfo(‘url’); ?>"><br> <input type="text" name="
   s" id="s" size="20" onfocus="this.value=”" value="<?php if (!$s) { $s = " -Search
   4cr-"; } echo $s; ?>" /><br> </form>
 * Ive tried putting the above code into a file called search.php and using the 
   mclude, but I just cant figure it out. Any help would really be appreciated! 
   Thanks.

 * Same problem. This is what I use:
    ` <!--mfunc get_useronline() --> <div id="
   useronline-count"><?php get_useronline(); ?></div> <!--/mfunc-->
 * But I get error:
    ` Fatal error: Call to undefined function: get_useronline()
   in /home/.irene/easydoesit/easydoesituniversity.com/wp-content/cache/wp-cache-
