How do you call each instance and get the numeric value to calculate a total value? I'm stuck at identifying the syntax for each instance's value - here's the script for the calculated field: var f = guideRootPanel.tblAgencies.Agency.instanceManager.instanceCount;var total = 0; for (var i=0; i < f; i++) { total = total + guideRootPanel.tblAgencies.Agency(i).ContractID.value; } this.value = total;
