JAVASCRIPT for SUM in Functional Attributes


I'm trying to create and attribute [Unemployed Total] in Feature Analyzer from two records: Unemployed_M, Unemployed_M, both are smallint data type


return currentRecord["Unemployed_M"] + currentRecord["Unemployed_M"];


That seems to create a string containing both records, for example Unemployed_M=4, Unemployed_M=7, the total = 47 insterad of 11

When I use the same code but do the substraction: 


return currentRecord["Unemployed_M"] - currentRecord["Unemployed_M"];


I'm getting the correct total (-3).


Can somebody advice me on the correct script to get to sum two records please.

Hi Kamila,


According to the suggestions here:



You could try this:

return currentRecord["Unemployed_M"]*1 + currentRecord["Unemployed_M"]*1;
