I downloaded data (single year 2013) containing “hispan” but did not also get the detailed variable “hispand”. Is the detailed variable not available for that dataset?
I was unable to replicate your issue. I was able to revise your data extract, reselect the HISPAN variable, and confirm that HISPAND appeared in the variable list for your data extract. I recommend that you follow this same process to get HISPAND in your extract.
Hope this helps.
