Not offhand.  What is it doing that's different from what you expect?
Is the whole program something you can show?  It'd be a lot easier if I
could see more of the context.

Offlist if you like; I don't see anything in the headers to make me
think you'll have any trouble reaching me, but you never know....

Did you try if ($4 == "") { ... }?  I don't expect that to help,
though; I suspect the actual problem is elsewhere (which is why I want
to see more context).
