The Value expression for the text box specifies a scope that is not valid for a nested aggregate.

Hi Sam,

Try this,

=sum(Sum( Code.Divide(   sum(Fields!WeeklyUnits.Value),Sum(Fields!EstUnits.Value)     ))
*   Sum(   Code.Divide(  sum(Fields!EstHours.Value),Sum(Fields!EstHours.Value,"Job")     )))
