No it isn't. I pay my bills ahead as much as possible -- an old habit from years of consulting work and irregular income. A zero bill simply means that my advance payments have been used up and my bill is paid this month. A NULL means the bill has not arrived yet, so I had better be ready to take action. Big differences in how I account for my expenses. Received on Wed Jul 02 2008 - 10:00:19 CDT
