Zonal Statistics Confusion

I am attempting to use zonal statistics with 2 layers: one raster DEM and a polygon shapefile with categorical info of moss types (I've also converted this into a raster with numerical values representing each type instead, not sure which works more effectively) and I want to find out the mean elevation for each type of moss.  When I run zonal statistics, however, the output layer is essentially just a replication of the moss type layer. 

I'm assuming this isn't just coincidence.  I'm thinking that I may have entered the layers in the wrong input spots for the zonal statistics tool.  Any tips on how to go about this properly?
