Bidirectional Reference/Label Commands

I've written a synopsis section for each chapter of my thesis, and I'd like to refer to various sections or subsections using \label and \ref commands. However, since the synopsis precedes the chapter, I'm getting errors simply because the relevant \ref commands precede the \label commands.

Is there a simple work-around to allow for bidirectional referencing?

Thanks!

This shouldn't cause errors, so you must be doing something else. Can you provide a minimal example of what doesn't work. (You need to run latex at least twice to resolve the references; I'm assuming you're doing that?) – Alan Munn Jul 9 '11 at 3:09
Correct! I had to run in 4 times to take. Thank you. – user02138 Jul 9 '11 at 3:49

There should be no problem with forward references. However, it may take a number of latex runs to resolve all of the references. Usually two runs is sufficient, but more are sometimes necessary.
