You know how people keep asking you to do the same thing ? And they ask again and again and again? And you never quite do exactly what they're asking? And even when the problem was solved two days ago, you still can't see it? The two things are connected Now, can you or can you not post 20 lines of code that runs and reproduces the problem (self-contained bug report)?

I don't know how to answer you. I ran the little code blocks that were posted and they ran fine with no error.

Please explain how: And even when the problem was solved two days ago, you still can't see it?

Tell me again and I will implement "the change" required.

So a made a little pair of units and the variable is passed.



#!/usr/bin/perl
use strict;
use warnings;

use manageusers_2 qw($LoggedOn_user_id);

print "$LoggedOn_user_id\n";

And 


#!/usr/bin/perl
use warnings;
use strict;

package manageusers_2;

BEGIN {
    use vars qw($VERSION @ISA @EXPORT);
    use DBI;

#    $ENV{DBI_TRACE}=1;
#    $ENV{PERL_DBI_DEBUG}=1;

    require Exporter;

    @ISA = qw(Exporter);

    # exported functions
    our @EXPORT_OK = qw($LoggedOn_user_id);
    $VERSION = '0.0.1';
}

our $LoggedOn_user_id=428;
1;

I made sure the aparameters in my real program were the same

It failed

$userid_1 = $manageusers::LoggedON_user_id;
warn("userid : '$userid_1' ");

And the result is:
