Copy table values to new instance of table

Good Morning.

I have a flowed form that looks like this.

form1

        Subform1

                       ACT (ExpandableTable)

                              Header

                              Row1

                              Row10

                              Footer

                                         button

when the button in the footer is clicked a popup menu appears where users can insert a new instance of the Table, Copy current section, or delete current section. I have not been able to copy the values from the previous instance successfully when the copy current section is chosen. All fields need to be copied and there is probably 20 fields in all. Also how would I insert a new blank instance between two instances?

Here is the click event I have so far.

var cChoice = app.popUpMenu("Add a blank section",  "Copy this section", "-", "Delete this section");

if (cChoice == "Delete this section"){

_ACT.removeInstance(ACT.instanceIndex);

}

else if

(cChoice == "Add a blank section"){

_ACT.addInstance(ACT.instanceIndex);

} else {

var intCount = xfa.resolveNode("ACT").instanceManager.count; xfa.resolveNode("ACT").instanceManager.addInstance(1);

xfa.resolveNode("ACT.Row1[" + intCount.toString() + "].AssetClass").rawValue = xfa.resolveNode("ACT.Row1[" + (intCount - 1).toString() + "].AssetClass").rawValue ; }
