When following the Aggregating Data section in the Building Damage tutorial located at:
https://opensource.ncsa.illinois.edu/confluence/display/ERGO/Building+Damage

I was unable to set a Ranged Style similar to the tutorial. I was able to set a simple style but this may not be an appropriate representation of the building damage by census tract.
