Try using the plots option in SPSS. Put one factor on the x-axis and the
other in the separate lines box. Significant intercations will show up as
non-parallel profiles while non-significant interaction will exhibit
approximately parallel parofiles. You should be able to work out the nature
of the interaction from the plot.
