It is an error but the two statements in the book are equivalent:<br><br>pg 88<br><br>if ($Transaction->CreatorObj->id != $RT::Nobody->id){}<br><br>pg 89<br><br>unless ($Transaction->CreatorObj->id == $RT::Nobody->id){}

I see. I also hadn't noticed that the comparison operators had been changed as well.<br>
<br>
New question: On page 88, right after that if statement, in the next
line, that starts off "my $user", shouldn't that first 'RT' in the line
have a dollar sign in front of it, or is my lack of perl knowledge
showing through too much? :)<br>
