I am currently working on a raffle script to raffle off items. I am working on making it so it checks to see if the email submitted is not already in the db. if it is.. it denys the user, but if its not, it adds it. This code does work "sorta". The code will add the user but its not kicking out my submission if the email is already in the db. It just adds it again. If anyone knows a way of doing this, it would be greatfully appreciated.

open(RAFFLE_DAT,"< tickets.dat") || die "tickets.dat is not found.";
while (defined($line=<RAFFLE_DAT>)) {
($tickennum,$emailaddr)=split(/::/,$line);
if ($emailaddr eq $email) { &bademail();
}
else { &goodemail();
}
close (RAFFLE_DAT);
}
