code is being rendered when I don't want it to be

I am attempting to post a how-to regarding a simple web application I created. Problem is I am trying to post the raw code, but WP is rendering the code instead of just displaying it. I have the in place so not sure why it is doing this. Any ideas? Here is the ode I want to just display as text.

<form id="sports" action="Query.php" method="POST" name="sports">Select a Sport
<select name="category_id"> < ?php</select> <select name="category_id"> $sql = "SELECT category_id, sport FROM sports ".</select> <select name="category_id">"ORDER BY sport";</select>$rs = mysql_query($sql);
while($row = mysql_fetch_array($rs))
{
echo "".$row['sport']."\n "; } ?>
<input type="submit" name="submit" value="Select a Sport" /></form>
