Default assistance writing code for a javascript arrray

I need assistance writing code for a javascript array in an asp page..
I have created a two-dimensional array that stores data from a database table. The array consists of the following fields.

emp_id, emp_name, supervisor, manager

var REPRELATE = new Array();
REPRELATE[0]= new Array("123456","Jones, Carol","Smith ,Michelle","Lesley,Patricia",);
REPRELATE[1]= new Array("126655","Hamelton, Denise","Hunter,Anne","Rose,Krista",);
REPRELATE[2]= new Array("127755","Cooper, Helen","Franks,Vicki","Edwards,Annika",);
REPRELATE[3]= new Array("127884","Howard, Elizabeth","Sharne,Avis","Preay,Darryl",);
REPRELATE[4]= new Array("127943","Jackson, Jill","Franks,Vicki","Edwards,Annika D",);

I want a drop down box that populates with the emp_name (using a recordset) then match the drop down selection with the same emp_name in the array.
Once the emp_name is selected from the drop down the emp_id value is passed to a hidden field and the supervisor and manager of the employee is automatically populated in text boxes "txtSup" and txtMan. Can you please assist with the code for what I am trying to do?

try the following approach, there are probably many more cleaner ways to do it:

<html>
<head>
<script language="javascript">
var REPRELATE = new Array();
REPRELATE[0]= new Array("123456","Jones, Carol","Smith ,Michelle","Lesley,Patricia");
REPRELATE[1]= new Array("126655","Hamelton, Denise","Hunter,Anne","Rose,Krista");
REPRELATE[2]= new Array("127755","Cooper, Helen","Franks,Vicki","Edwards,Annika");
REPRELATE[3]= new Array("127884","Howard, Elizabeth","Sharne,Avis","Preay,Darryl");
REPRELATE[4]= new Array("127943","Jackson, Jill","Franks,Vicki","Edwards,Annika D");

function addOption(whichDD,name,value)
{
    // create a reference to the SELECT and the form
    var theDD=eval(whichDD);

    // create the new OPTION
    var newOption;
    newOption= new Option (name,value);

    // position
    var insertAt = theDD.options.length;

    // create the space
    theDD.options.length=theDD.options.length + 1;
      // add the option
    theDD.options[insertAt] = newOption;
}

function myDD_onChange()
{
    // get the current value
    var curIndex=document.myForm.myDD.value;

    // populate the fields
    document.myForm.txtSup.value=REPRELATE[curIndex][2];
    document.myForm.txtMan.value=REPRELATE[curIndex][3];
    document.myForm.empID.value=REPRELATE[curIndex][0];
}
function showDDElements()
{
    // Display the name and use the value as the index for the array REPRELATE
    for (count=0;count<REPRELATE.length;count++)
    {
        addOption(document.myForm.myDD,REPRELATE[count][1],count);
    }

}
</script>
</head>
<body onload="showDDElements();">
<form name="myForm">
<select name="myDD" onchange="myDD_onChange()">
</select><br>
<input type="text" size="20" name="txtSup"><br>
<input type="text" size="20" name="txtMan"><br>
<input type="hidden" size="20" name="empID"><br>
</form>
</body>
</html>
