Problem with mysql UPDATE query

Hi everyone,
Is there something wrong with this query? it will not update the table, even though all the variables are fine.

mysql_query('UPDATE Blog
	SET Title="$title", Post="$post"
	WHERE id="$entry"');


Try switching the single and double quotes around.

thanks, i ended up doing that and just separating it like this:

$updateQuery = "UPDATE Blog 
	Title = '$title',
	Post = '$post' 
	WHERE id = '$entry'";
	$update = mysql_query($updateQuery, $con);

and it worked.
