Hidden subform connected to dropdown object

[DKinsley]

I have a drop-down list object labeled "Question" that contains items: Yes, No, N/A

When the user selects "Yes" the hidden sub-form becomes visible.

That sub-form contains three text-fields.

If the user types data into any of these three text fields and then changes their mind and selects either "No" or "N/A" from the drop-down, I want to delete and data that was entered into the text-fields in the sub-form then hide the sub-form.

This is the script I am using but when the user is warned they about to delete the data they entered into the 3 text-fields and they choose No - they do not want to continue, the drop-down goes to "No" anyway even though i have the script that says to make it go back to "Yes". What am I doing wrong?

Form1.Table1.Row[0].Question::change - (JavaScript, client)
if ($.boundItem(xfa.event.newText) == "Yes"){
this.resolveNode("Additional00").presence = "visible";
}
if ($.boundItem(xfa.event.newText) == "No"){
var nResponse = xfa.host.messageBox("If you entered anything in the Supplier Description, SupplierReason or SupplierSubstantiation text fields it will be deleted. \n\nDo you want to continue?", "Deleting Data", 1, 2)
if (nResponse == 3){
($.boundItem(xfa.event.newText) == "Yes");
}
if (nResponse == 4){
this.resolveNode("Additional00.Subform4.SupplierDescription").rawValue = null;
this.resolveNode("Additional00.Subform4.SupplierReason").rawValue = null;
this.resolveNode("Additional00.Subform4.SupplierSubstantiation").rawValue = null;
this.resolveNode("Additional00").presence = "hidden";
}
if (xfa.host.version < {
xfa.form.recalculate(1);

Hi, 

you can do this with much less code. Also, the messageBox methods returns 4 when pressing the Yes-button. 

var cSel = xfa.event.change, // current selection
	cPrevSel = xfa.event.prevText; // previous selection

if (cSel === "Yes") {
	Additional00.presence = "visible"; // show subform
} else if (cSel === "No" && cPrevSel !== "No") {
	if (xfa.host.messageBox("If you entered anything in the Supplier Description, SupplierReason or SupplierSubstantiation text fields it will be deleted. \n\nDo you want to continue?", "Deleting Data", 1, 2) === 4) {
		Additional00.presence = "hidden"; // hide subform
		xfa.host.resetData(Additional00.somExpression);	// reset subform data
	} else {
		xfa.event.change = cPrevSel; // restore previous state, if user selected no
	}
}

This works great - thank you
