Styling fusion table layers polygons

[UrilmSmam]

I have a fusion table with 5 populations (columns), for each these I want to display the polygons with the highest concentration of population in a different color.In the example for styling fusion table layers, the "polygonOptions" was defined, but I don't want the polygons to have any styling unless there's a concentration of one of the populations, and also because that would take 1 style away from the limit of 5.I'm not sure what to change or what I'm missing to have these styles display correctly.My map: http://seflculturemap.com/miami-test.html
