Mysql error need help quick :(

[Anon]

I have a php script that inserts data in a table. It used to work. Now it doesn't.
Here are the lines in question. The variables that aren't defined in there have been passed on via a form.

$ip=$REMOTE_ADDR;
$answered="n";
$message=addslashes($message);
$sql=mysql_query("INSERT INTO question (name, message, email, ip, answered) VALUES ('$name', '$message', '$email', '$ip', '$answered')");

and here is the error.
Warning: 0 is not a MySQL link index in /home/slangdes/slangdesign-www/advice/input.php3 on line 8

Warning: Cannot add more header information - the header was already sent (header information may be added only before any output is generated from the script - check for text or whitespace outside PHP tags, or calls to functions that output text) in /home/slangdes/slangdesign-www/advice/input.php3 on line 9

Line 8 is the last line of my code.

have you opened up a thread into the database? By using something like:
mysql_connect($host,$user,$password);

You need a connection into the database before doing any queries.

Otherwise, confirm the exact query that you are attempting to execute, maybe one of your variables is incorrect. Echo the query statement for verification.
