Simple Effects Analysis SPSS


I missed this weeks tutorial at my university on how to use SPSS for simple effects analysis. I currently have a two-way factorial ANOVA. My first variable has 2 levels. My second variable has 3 levels. My question to you is, what is the syntax I would use to compare the 3 levels of the second factor within eachother? I know I may have to use the MANOVA approach. I've googled this a million times and I can't find a clear cut answer. Can someone please please help.
