leave out echo . btw a meta key argument is required from what I remember –  onetrickpony Dec 17 '10 at 14:13
    
Yea, leave out echo but you need more than just get_post_meta. It has to be get_post_meta($post->ID, 'change-this-to-your-meta-field', true); –  eileencodes Dec 17 '10 at 14:56

Remove the echo. In PHP, you only use echo when you want to send the result as text to the browser. If you want to use the value in PHP (like you are trying to do), then you leave out the echo and add $post->ID, 'meta_field_you_want', true to get_post_meta();

<code>$meta = get_post_meta($post->ID, 'your_key', true); $feed = "twitter.com/statuses/user_timeline/$meta.rss";; $doc->load($feed); </code> –  Don Gilbert Dec 17 '10 at 17:34

Might want to add some error handling, too: if ( $meta = get_post_meta($post->ID, 'your_key', true) ) { $feed = "http://twitter.com/statuses/user_timeline/$meta.rss"; $doc->load($feed); } ... so it doesn't break if that key isn't present. –  goldenapples Dec 17 '10 at 21:33
