Resolve Nodes - For Loop - Instance Manager Please Help

Question

Hello,
I made a table in lifecycle designer that uses the instance manager to add rows.
I want to write code that will loop through each of the instances and perform a comparison.  I would like the code to examine the index field.  If the index field = 2,  then return the value of the num amount field.
This is what I have tried so far and it does not work. 
var
 var
var
oFields = xfa.resolveNodes("Subform1[*].index1");
var     
nNodesLength = oFields.length;
for     (var nNodeCount = 0; nNodeCount < nNodesLength; nNodeCount++)
  if (oFields.item(nNodeCount).rawValue ==2)     {
     form1.#subform[2].Table5.Row5.NumericField1.rawValue
     = form1.Page1.Subform1.Capital1.Capital1.detail.numAmount.rawValue;}
break;

Here is a more lengthy definition of my problem.   I hope someone can help. 
1.     I have a table that will allow the user to add rows when they click the plus button.  Here is the code
----- form1.Page1.Table7.#subformSet[0].#subformSet[1].detailHeader2.Button2::click: - (JavaScript, client)
_detail.addInstance(this.parent.index);
//Invoke the recalculate method to include the field values from the added row in calculations.
xfa.form.recalculate(1);
2.     The table also has a button to delete rows.   Here is the code
----- form1.Page1.Table7.#subformSet[0].detail.Button2::click: - (JavaScript, client) --------------
// Invoke the Instance Manager to remove the current instance of the detail subform.
_detail.removeInstance(this.parent.index);
// Invoke the recalculate method to update the form calculations.
xfa.form.recalculate(1);
3.     The table has a drop down list named txtPartNum and that allows you make a selection.  Once you have made the selection a script populates other fields in the same row. The Drop Down list contains this code:
----- form1.Page1.Table7.#subformSet[0].detail.txtPartNum::initialize: - (JavaScript, client) ------
// Populate the part number Drop-down List.
partNoScript.populatePartNo(this);
----- form1.Page1.Table7.#subformSet[0].detail.txtPartNum::change: - (JavaScript, client) ----------
// Populate the description and the unit price when we change the part number.
partNoScript.getDesc(xfa.event.newText, txtDescription, numUnitPrice, index1);
4.     The following script populates the following fields:
txtPartNum,
txtDescription,
numUnitPrice,
index1
----- form1.#subform[2].#variables[0].partNoScript::partNoScript - (JavaScript, client) ------------
// This script object controls the interaction between the part number, description and unit price fields.
// When you fill the partNo, partDesc and partPrice arrays, make sure they have the same number of array indices in
// each array i.e. for every part number, there should be a matching description and price.
// Array of part numbers.
// This script object controls the interaction between the part number, description and unit price fields.
// When you fill the partNo, partDesc and partPrice arrays, make sure they have the same number of array indices in
// each array i.e. for every part number, there should be a matching description and price.
// Array of part numbers.
                     var partNo = new Array(" ",
