G'day Joe

It'd be nice to have a little more data. I think your __DIE__ handler is a great idea, but it's obviously not showing up the error. I can't tell you why. It looks like your code is getting a warning for no reason, but I can't tell you why that is so.

I have occasionally got HASH reference errors for nothing to do with hashes before and it's usually because I've forgotten to close some quotes or put in a semi-colon or whatever.

Nevertheless, I'm curious what your code returns for the following (just drop this in place of the segment you cut'n'pasted for us above): 

use Data::Dumper;

                # Just grabbing the values of these so that
                # strict will cope with them.
my $my_today_int = $today_int;
my $my_no_call_requested_days = $no_call_requested_days;
my $my_i = $i;
my $my_user_id = $user_id;
print STDERR Dumper($my_today_int, $my_i, $my_user_id);
print STDERR Dumper($my_no_call_requested_days);
{
        use strict;
        my @today = @{$my_no_call_requested_days->{$my_today_int}};
        print STDERR "today:\n", Dumper(@today);

        my $ref = $today[$my_i];
        print STDERR "ref:\n", Dumper($ref);

        my $employee_id = $ref->{'employee_id'};
        print STDERR "employee_id: [$employee_id]\n";

        if($employee_id eq $my_user_id)  # should be "=="
        {
                print "They are the same!\n";
        }
}

It's functionally the same. This block is strict compliant and all the interesting values are printed to STDERR so that we can see things as they go on.

Hopefully rewriting to something like this will help identify the problem. Particularly if the bug is a missing close quote or } or similar above. :)

Hope it helps.
