Deleting a row from a MySql Table

Im making an admin panel and when I try to delete a news post I hit the delete link and it should go through it all ok, and it does in sense. It shows no error, but it always says: You must have made a mistake in using this page. Do you see anything in there that is causing it to not get the id?


<?php
	ini_set ('display_errors', 1);
	error_reporting (E_ALL & ~E_NOTICE);
	
	if ($dbc = @mysql_connect ('localhost', 'root', '')) { 
		if (!@mysql_select_db ('news')) {
			die ('Could not select the database because: <b>' . mysql_error() . '</b>');
		}
	} else {
		die ('Could not connect to MySQLbecause: <b>' . mysql_error() . '</b>');
	}
	
	if (isset ($_POST['submit'])) {
	
		//Define the query
		$query = "DELETE FROM news_entries WHERE news_id={$_GET['id']}";
		$r = mysql_query ($query); // Execute the query.
	
		//Report result
		if (mysql_affected_rows() == 1) {
			print '<p>The Blog Entry Was Deleted</p>';
		} else {
			print "<p>Could not delete the entry because: <b>" . mysql_error() . "</b>. The query was $query.</p>";
		}
	} else {
		//Display the entry in a form
		if (is_numeric ($_GET['id'])) {
			//Define the query.
			$query = "SELECT * FROM news_entries WHERE news_id={$_GET['id']}";
			if ($r == mysql_query ($query)) {
				$row = mysql_fetch_array ($r);
				
				//Make the form
				print '<form action="deleteentry.php" method="post">
				<p>Are you sure you want to delete this entry?</p>
				<p><h3>' . $row['title'] . '</h3>' . $row['entry'] . '<br />
				<input type="hidden" name="id" value="' . $_GET['id'] . '" />
				<input type="submit" name=submit" value="Delete this entry." /></p>
				</form>';
			} else {
				print "<p>Could not retrieve the entry because: <b>" . mysql_error() . "</b>.";
			}
		} else { // No Id Set
			print '<p><b>You must have made a mistake in using this page.</b></p>';
		}
	} // End main IF
	mysql_close();
	
	?>
