varför får jag följande felmedelande: 

Warning: Supplied argument is not a valid MySQL result resource in c:\\apache\\htdocs\\play3r\\forum\\inlagg.php on line 20

Warning: Cannot add header information - headers already sent by (output started at c:\\apache\\htdocs\\play3r\\forum\\inlagg.php:20) in c:\\apache\\htdocs\\play3r\\forum\\inlagg.php on line 23

av denna kod:

1\<?
2if(isset($laggtill)){
3if($vad=="trad"){
4if(isset($ruta)&& isset($rubrik)){
5$query = mysql_query("insert into inlagg set svar='nej' and fid='$var' and rubrik='$rubrik' and inlagg='$ruta', and av='$forumusername' and datum='date('Y-m-d H:i:s')',ikon='$radiobutton'");

1) Det är något fel i din sql-sats på rad 19

```
$valj2 = mysql_query("select id from inlagg where sid='$trad' and fid='$var' and av='$forumusername' and inlagg='$ruta'") or die(mysql_error());
```

 
2) Beror på att du skriver något till formuläret (HTML/echo/print) innan du anropar header. Du kan buffra output
