HTML FORM and PHP MYSQL Delete stumper

I know this should be easy but it isn’t…here is a code snippet

[code=php]<?php
mysql_select_db($d, $w);
$query_buysell = “DELETE FROM buysell WHERE passcode = ‘ <what goes here> ‘”;
mysql_query($query_buysell, $w) or die(mysql_error());
?>

….

<p>Please enter your passcode:</p>
<form name=”form1″ method=”post” action=”<?=$PHP_SELF?>”>
<p>
<input type=”text” name=”code”>
</p>
<p>
<input type=”submit” name=”Submit” value=”Submit”>
</p>
</form>
<p>&nbsp;</p>
[/code]

I have a form that takes a user inputted passcode…I’m trying to pass it in to the SQL query at the top of the program…<what goes in here>…I tried $_POST[‘code’] but it gives me a blank screen when I run it…it sounds like an easy fix but I’m stumped…any help would be appreciated.
