sum(group,value)

This computes the arithmetic Number sum of every value in a group. See sum_if() for a related conditional operator.

group describes the notes to be examined and may be any group designator including a find() query.

value can be any expression, but is typically an attribute value.

For example,

sum(children,$WordCount) 

constructs the current word count of the children of the note.
