Selective Reset of a form

I am working on a Supplier feedback form.

Stared in Adobe and then finished in LC Designer.

Problem. If they wish to provide more than one response, I do not want to clear the small group of demographic entrys.

Tried to use Adobe and the look at using the reset action command , thinking I could select the fields I wanted or did not want to clear. Opps, can not edit in Adobe Pro and more, only LC Designer.

Started reading... Again.

Example 1.

Select fields to be reset and reset them.
var fields = new Array();
fields[0] = "P1.OrderForm.Description";
fields[1] = "P1.OrderForm.Qty";
this.resetForm(fields);

The same fields can be reset using only one line of code:
this.resetForm(["P1.OrderForm.Description","P1.OrderForm.Qty"]);

Example 2.

This example shows how to reset a whole subtree. For example, if you pass “name” as part of the fields array, all name fields, such as name.first and name.last, are reset.
this.resetForm(["name"]);

However, not being aware of all this before hand... means I do not have sub trees ? I could group in a sub form, but I want this group to remain, the rest of the form to be reset.

Can some one provide some guidance to me as to how I can reset a form, but EXCLUDE 4 Fields.

Thanks
