Problem using CASTed timestamp column

Hi all,

  I've got an odd problem. I've got a column with a non-standard
date/time in it that I carve up and re-cast as a timestamp. This works
fine. Now though, I am trying to check/restrict my results to dates
before now() and it's telling me that the columns doesn't exist.

  Any hints on what I am doing wrong?

Thanks!
