Svar venligst per e-mail, men ellers her i i gruppen.
På forhånd tak

Jeg tror, problemet er, at PHP på din server er sat op til at udskrive
bemærkninger (notices), når en variabel ikke er sat. Det kan (vistnok)
slås fra sådan her (indsæt koden øverst i scriptet):

error_reporting(E_ALL ^ E_NOTICE);

> Svar venligst per e-mail, men ellers her i i gruppen.

Niks. Hvis du vil have support uden selv at hjælpe andre i gruppen eller
i det mindste selv tjekke svarene i gruppen, så kan vi godt aftale en
timepris...

Det betyder, at du forsøger at læse en variabel, du ikke har defineret
forinden. En variabel defineres, når den tildeles en værdi.

Normalt vil PHP ikke brokke sig, når du forsøger at tilgå en
ikke-defineret variabel. Men din installation er åbenbart sat op til at
være mere kritisk. Dette kan ændres fra såvel htaccess-filer, i php.ini
og inde i selve dit script.

http://dk.php.net/manual/en/html/features.error-handling.html


Jeg kan nu anbefale at slå alle advarsler til. Dels er det med det til
at fange trykfejl under programmeringen, men det kan også være med til
at afsløre evt. sikkerhedshuller i din kode.
