Copy Instance Info - Help Niall

Question

My form has repeating instances. In some cases the addes instance is almost exactly like a previous instance. I would like an addInstance that would add the instance with the information from this.parent.index field if that is possible.
So when clicking on add instance it would prompt the user for the line number to be copied. If that's not possible, then copying the last line entered would be the workaround.
This is the last major piece of the puzzle for this form. The add instance I'm using now looks like....
this.resolveNode('Subform3.Subform2._Subform1').addInstance(1);if  (xfa.host.version < 8) {xfa.form.recalculate(1);}
Thanks -pc

Answer 1

I actually figured the one index myself belive it or not...
I've tried to extrapolate your example on copying a line but can't get it to run...am I close? I know my subform naming is causing this to be more difficult than it is probably....and the fact that I'm not very good at this (yet) doesn't help either...here is where I am....
form1.Subform4.Button3::click - (JavaScript, client)
// set up the question, based on the current number of rows
var 
vQuestion = "Select which row you want to copy. \n\nEnter a number between 1 and " + Subform3.Subform2._Subform1.count + ". \n\nClick Cancel if you do not want to copy an existing row.";
// add the new row
// '_' is shorthand for instanceManager, eg '_Row1'
Subform3.Subform2._Subform1.addInstance(
true); 
// ask which row the user wants to copyvar vTarget = xfa.host.response(vQuestion, "Copy a row") - 1;
// new rowvar vNewRow = Subform3.Subform2._Subform1.count - 1;
if (vTarget >= 0 && vTarget < Subform3.Subform2._Subform1.count){
// copy the value of the dropdown in the selected row
 var oItem = xfa.resolveNode("form1.Subform3.Subform2.Subform1[" + vTarget + "]").description.rawValue; 
// set the value of the dropdown
xfa.resolveNode("form1.Subform3.Subform2.Subform1["+ vNewRow + "]").description.rawValue = oItem; xfa.resolveNode("form1.Subform3.Subform2.Subform1["
+ vNewRow + "]").description.execEvent("exit");}
else if (vTarget == null || vTarget == -1){
// do not copy, but also do not give audio feedback
}else{
xfa.host.beep("1");// warn the user if number is outside range
