ODBC Problem

Hi I get this error "
Warning: SQL error: [Microsoft][ODBC Microsoft Access Driver] '' is not a
valid name. Make sure that it does not include invalid characters or
punctuation and that it is not too long., SQL state 37000 in SQLExecDirect
in D:\Apache\Apache2\htdocs\redirect\add.php on line 16
"when i try to run an sql statement. The sql statement is INSERT INTO site
(site_name, site_url) values ("google", www.google.com); which I know is
correct because in Access if I run that exact statement it works perfectly.
The code is as follows:
---------------------------
<?php
$Site_NAME = $_GET['name'];
$Site_URL = $_GET['url'];
$conn = odbc_connect('redirect','','');
if($conn <= 0){
echo "Error in connection<BR>";
exit;
$Site_URL = "/forum/error.php?err=500";
}
else{
$query = "INSERT INTO site (site_name, site_url) values (\"". $Site_NAME .
"\", \"" . $Site_URL . "\");";
echo $query;
$result = odbc_exec($conn, $query);
}
include("reload.tpl");
?>
---------------------------
The values are passed to this file from a different file. I know everything
else is working because the SQL statement I tested in Access is $query which
is echoed out to the screen. Any ideas?
Thanks.
