 * Hey ,
 * I am running XAMPP latest version and WP 3.0.
    **Problem** When I try to use 
   query_posts() for retrieving posts by slugs. I am getting this error
 * Warning: trim() expects parameter 1 to be string, array given in C:\xampp\htdocs\
   wordpress\wp-includes\query.php on line 1272
 * for code
    <backticks> <?php
 * get_header();
    query_posts(array(‘name’=>array(‘guitar’,’movie-post’)));
 * if (have_posts()) :
    while (have_posts()) : the_post(); the_content(); endwhile;
   endif; get_sidebar(); get_footer(); ?> I</backticks>
 * What is wrong with this ? If I cannot use this , can you please suggest alternatives?
   This works when I put query as ‘name=guitar’

 * There isn’t a parameter called ‘name’:

 * ‘name’ only allows one entry:
    [http://codex.wordpress.org/Function_Reference/query_posts#Post_.26_Page_Parameters](http://codex.wordpress.org/Function_Reference/query_posts#Post_.26_Page_Parameters)
 * try and use the post ids instead with the `post__in=array(3,7)` parameter.
