I have some Perl code where I am trying to return a value from a subroutine, but I'm getting all kinds of errors. Here is the code I have:

while($sth->fetch())
{
# if($leventid == 2||3||4||11||21) {
# $pagecount++;
# }
$page = get_timing($leventid, $tid, $tname);
if($page == 1) {
return 2;
} else {
return 0;
}
}

#if($page == 1) {
# return 2;
#} else {
# return 0;
#}

#print "Total # of pages: $pagecount\n\n";

sub get_timing($$$) {
my $event_id = shift;
my $task_id = shift;
my $task_name = shift;

$event_id = int($event_id);

if($event_id == 2) { #missed start date
print "$task_name returned an error code of $event_id.\n";
$p = 1;
}
if($event_id == 3) { #missed end date
print "$task_name returned an error code of $event_id.\n";
$p = 1;
}
if($event_id == 4) { #missed due date
print "$task_name returned an error code of $event_id.\n";
$p = 1;
}
if($event_id == 11) { #missed due date
print "$task_name returned an error code of $event_id.\n";
$p = 1;
}
if($event_id == 21) { #missed due date
print "$task_name returned an error code of $event_id.\n";
$p = 1;
}
return $p;

} #end get_timing

These are the errors I'm getting:

main::get_timing() called too early to check prototype at exportmonitor.pl line 46.
Can't return outside a subroutine at exportmonitor.pl line 48.

What am I doing wrong, and why isn't the value of $p being stored in $page above?

Got this from perldiag - various Perl diagnostics (http://www.xav.com/perl/lib/Pod/perldiag.html)

I'm not a Perl expert, but it sounds like you need to move the function up higher in the code file.

You've called a function that has a prototype before the parser saw a definition or declaration for it, and Perl could not check that the call conforms to the prototype. You need to either add an early prototype declaration for the subroutine in question, or move the subroutine definition ahead of the call to get proper prototype checking. Alternatively, if you are certain that you're calling the function correctly, you may put an ampersand before the name to avoid the warning. See the perlsub manpage.

Also, your "return 2" and "return 0" can not be used inside the main portion of your code, only from inside a subroutine. Maybe you want to use exit instead?
