Issue with Stored Procedure modify in SQL

Trying to amend a stored procedure and getting this error

Msg 156, Level 15, State 1, Procedure webopius_OrderExport, Line 14
Incorrect syntax near the keyword 'left’.

The code is

ALTER proc [dbo].[webopius_OrderExport]

   SET NOCOUNT ON
BEGIN

      convert(varchar, getdate(), 103) ExtractDate,

   FROM 
      dbo.Orders o with (NOLOCK)
   left join 
      orders_ShoppingCart os WITH (NOLOCK) ON os.OrderNumber = o.OrderNumber   
   left join 
      Customer c WITH (NOLOCK) on c.CustomerID = o.CustomerID 
   left join 
      Product p with (NOLOCK) on p.ProductID = os.ProductID
   left join 
      ProductManufacturer pm with (NOLOCK) on pm.ProductID = os.ProductID
   left join 
      Manufacturer m with (NOLOCK) on m.ManufacturerID = pm.ManufacturerID 
   left join 
      Address a with (NOLOCK) on a.AddressID = c.ShippingAddressID 
   WHERE 
      o.OrderNumber = os.OrderNumber 
      AND o.ShippedOn IS NULL 
      AND (o.TransactionState IN ('AUTHORIZED', 'CAPTURED') 
           OR (o.TransactionState = 'PENDING' and o.PaymentMethod='PURCHASEORDER'))
      AND IsNew = 1
      AND o.StoreID <> 4
   ORDER BY 
      ordernumber
END

The column does exist in the SQL table where the left command is shown.

Any ideas where I'm going wrong?
