My first guess is that the file needs to be in the "files" directory for drupal to have access to it. Is var/paystubs/$uid what the is set as the "files" directory in Drupal? When you upload files using the interface do they end up in var/paystubs/$uid.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
