I'm trying to sum a computed property (effectively sum a column in a table), but it returns 0 (Total Net - bottom of last column). See fiddle: https://jsfiddle.net/2djreyds/ I think it has to do with how I am referencing the computed property. Sure its something simple! Any ideas? or if there's a smarter way to do this let me know! :) Thanks!
