You are on the right track.  Let's say that RrSS is the male.  Then your RS, RS, rS and rS that you have at the top are the sperm. (male gametes)  The Rs, Rs, rs, rs are the unfertilized eggs of the female.  The 16 boxes are the possible "babies" that the possible gametes could create.  So, like someone else said, you work the cross.  If RS sperm combines with Rs egg (that is the first box) then the baby is RRSs.  When you are done with the cross, count how many boxes have each geneotype (exact same spelling) and how many boxes have babies that look the same (phenotype)  That's it!
