adding code tags to posts

Not sure if this is the right section but am I adding code tags properly to the posts.

It is just when it parses the html entities don’t get shown in plain text.

Am I doing something wrong?

<?php /*Quick short code test snippet*/
function piecemaker_shortcode( $atts, $content = null )
{
  return '<div id="piecemaker?&gt;';

}

add_shortcode( 'piecemaker', 'piecemaker_shortcode');

?&gt;

The problems seems to occur here:

Just don’t put the PHP tags – best way to go about it.
