[nfbcs] Failing If Statement

[Lanie Molinar]

Hi. I'm sending this again since I accidentally hit reply instead of 
reply all. Thanks for the help. I knew not to put a ; at the end of an 
if statement and don't remember putting one there, but I must have at 
some point, and just didn't notice. I'm using my school's Linux lab 
remotely, so I'm not sure what version of G++ it uses. I'll have to try 
that and see if it works. That's good to know. It's so easy to miss 
those little errors like extra ;'s.
