Here is the form with the script in KPI 1 thru 3

Not sure it saves you a lot but here is an option. 1. create a script object to set the rating fields as required or optional based on 3 parameters:   - the page number   - the object number   - the status of KPI (empty or not)2 include a script in the exit event of each KPI field to test if KPI is ...

would you want to share the form?

what if you re-define sTarget as var sTarget = "object"+i+".kpi"+i;... if(this.resolveNode(sTarget).rawValue == null){ ...

There are exceptions to that I believe: if the script is included in a script object or attached to an object of the master page, I believe the complete SOM would be needed… but I’m not 100% sure. 

Regardless of the visibility of the dropdown field, the its value can be copied from the "Card" being duplicated. You can then set the visibility of the field depending on the value of that field or another field, or on the visibility status of the field in the card being duplicated,... or without c...

And now I realize the rating box fields also change numbers,... so here is a revised scriptfor (var i=1; i<=13;i++){  var sTarget = "object"+i;  var sTargetRatingBox_1 = sTarget+".Table1.Row1.ratingbox"+i+"_1";  var sTargetRatingBox_2 = sTarget+".Table1.Row1.ratingbox"+i+"_2";  var sTargetRatingBox_...

another thought though: since your fields have a default value (0), I think making these field "required" will visually show it, but it won't force the user to change the value of the field.  

I guess you could create a loop running through each object, i.e. from 1 thru 13, create a string variable to specify the targeted object and set the mandatory status using the resolveNode property. Something like:for (var i=1; i<=13;i++){  var sTarget = "object"+i;  if(this.resolveNode(sTarget).kpi...

Can you share your form again, and clarify further the expected behavior?
