help with lnk1104 error on .lib file

I am trying to build a project and get a lnk1104 error regarding a
file of the form .../../ ProjectName.lib No other errors, just this
one.
I've googled this error but not found anything useful at my newbie
level. I understand the issue may be one of including the right
files. I therefore went to Additional Include Directories on the
Property Pages but I would need help working out what I need to do to
verify that the paths there are correct.

Can anyone advise or provide a URL for this problem? Perhaps this
isn't a language question, and I apologise if I'm slightly OT but this
is a very urgent matter for me so I was keen to pick among the high-
activity newsgroups. If you think another ng would be more
appropriate, by all means say so. But bear in mind that, from a
poster's standpoint, it's better to get an answer quickly from a high-
activity newsgroup than to find an exactly-matching low-activity
newsgroup and get an answer in a month's time.

Thank you very much for your help,

Paul Epstein
