Yes, it's so easy to end up with an uneven number of square brackets, especially in nested quotations, although it's usually a good idea to shorten a quote to the relevant part of the post quoted. There are two main ways to quote pieces of text so that they will come out

If you are doing these things and still don't get quotations to show correctly, one possibility is that the individual posting does not have BBCode enabled. To enable BBCode by default, go to:
User Control (button at top right of CBB home page)
Edit Posting Defaults
Put a check in the box next to "Enable BBCode by default."
There is also an option below the box in which posts are entered that says, "Disable BBCode." If you have this checked, your quotations will appear showing command text rather than within a quote box.
