i am trying to set a embedded data like below but i m getting error of {Invalid Expression}.
DO1, DO3 and DO5 are embedded data which i have already set before the below line in survey flow. Any suggestion on why i am getting this error?
 

$e{ $e{ $e{ e://Field/DO1 } + $e{ e://Field/DO3 } + $e{ e://Field/DO5 } }/$e{ e://Field/count } }

Please some one help me on this.
