[ic] $Session->{username} in a Payment module?

[interchange-users@icdevgroup.org (Ron Phipps)]

Hello,

I'm trying to do the following in the signio payment module:

my $comment1 = $Session->{username} || $actual{b_fname};

However every time $comment1 is set the billing first name even when the
user is logged in.  Is there a restriction on using the $Session object
in the payment module?  If so how can I access the username in the
payment module?

Thanks,
-Ron
