In addition to Casper's nice explanation, Kristopher Hayes' homepage is a great resource for moderated mediation. He provides articles and a SPSS macro which may be helpful for you:

http://www.afhayes.com/spss-sas-and-mplus-macros-and-code.html#sobel

Just scroll down to MODMED and download the article and the SPSS macro. The SPSS macro conducts tests of conditional indirect effects when assessing moderated mediation, as described in Preacher, Rucker, and Hayes (2007).

HTH, Karin
