Over View: The ShipToTransferBillTo function 
is called with a user selects the checkbox indicating that the 
BillTo information is the same as the ShipTo information. By
deselecting the checkbox the BillTo fields are blanked out. One 
important feature to this code snippet is to name the form, "frmMain". 
The elements collection belongs to frmMain.
< form name=frmMain>
<input type=checkbox name=chkBillShipSame value=1 OnClick="ShipToTransferBillTo()">BillTo information is same as ShipTo
</form>
<script language="javascript">

function ShipToTransferBillTo()
    {
    	if (frmMain.elements("chkBillShipSame").checked==1)
        	{
        	frmMain.elements("txtBillToAddress1").value=frmMain.elements("txtShipToAddress1").value;
        	frmMain.elements("txtBillToAddress2").value=frmMain.elements("txtShipToAddress2").value;
        	frmMain.elements("txtBillToCity").value=frmMain.elements("txtShipToCity").value;
        	frmMain.elements("txtBillToZipCode").value=frmMain.elements("txtShipToZipCode").value;
        	frmMain.elements("txtBillToPhone").value=frmMain.elements("txtShipToPhone").value;
        	}
        	else
