Sender en form men fejl ved modtagelse

Hej Eksperter.
Håber nogen kan hjælpe da jeg er gået helt død i dette problem.
Har en form i ret.php som når jeg submitter sender videre til zip_upload_ret.php
Problemet er at den giver mig "Stort Problem" svaret.
---zip_upload_ret.php[Redigeret]:
if($_POST["action"] == "Submit")
{ /* Fjernet*/ }
else
{
echo "Stort Problem";
}
og her kommer så mig ret fil - fejlen ligger nok heri, men kan simpelthen ikke finde fejlen.
Håber at en eller andet kan give mig en hånd. Måske be- eller afkræfte at fejlen ligger i min - while ($data = mysql_fetch_row($result)) {
