Marsha - try here at this on-line manual: http://www.fil.ion.ucl.ac.uk/spm/doc/manual/results.htm there's a nice worked example on the use of conjunctions for SPM99. You may also want to surf the spm-mailbase for some recent posts by Matthew Brett and Tom Nicholls on an update they've put together for doing conjunctions in SPM2.
