scope issue C#, VS2008

In the C# code attached, when setting a breakpoint inside the foreach after the ItemNo = blah blah blah statement, in the immediate window I get

?ItemNo
The name 'ItemNo' does not exist in the current context

However, this returns the value I am looking for

?(string)LineItem.Element(sync + "Item").Element(sync + "ItemID").Element(sync + "ID").Value
"HEWC8011A"


What am I doing wrong?  VS2008

var LineItems = from el in ord.Elements(sync + "DataArea")
                 .Elements(sync + "SalesOrder")
                 .Elements(sync + "SalesOrderLine")
                                select el;

                string ItemNo = "";
                string loc = "";
                double qty_ordered = 0;
                double price = 0;

                foreach (var LineItem in LineItems)
                {
                    ItemNo = (string)LineItem.Element(sync + "Item").Element(sync + "ItemID").Element(sync + "ID").Value;

                    OrderHeader.OrdLines.Add(new OrderLine()
                    {
                        item_no = ItemNo,
                        loc = loc,
                        qty_ordered = qty_ordered,
                        price = price,
                        promDate = DateTime.Now.Date,
                        reqDate = DateTime.Now.Date,
                        reqShipDate = DateTime.Now.Date,
                    });

                    ItemNo = "";
                    loc = "";
                    qty_ordered = 0;
                    price = 0;
                }
