Are you saying that the mysql_query() causes the error? if so try
replacing the line with something like:
if (is_resource($connection)) {
$resultuv = mysql_query($uvquery, $connection);
} else {
echo "Problem with connection resource<br />\n";
var_dump($connection);
}
to get an idea of why
Also, what's in the connecttotaxa.php file? Is it just assignments of
$hostname, , $username, $password; or does it also make a connection. If
the former, then the file is confusingly named ;-)
