    Hi @manu ,
    According to your xml file, is it caused by the missing node Order?
    I made a test with a simple xml and I can get the values.
    Here is my code example:

    var xml = XElement.Load(@"C:\Users\Desktop\test.xml");  
            IEnumerable<XElement> de =from el in xml.Descendants("Header").Elements("EcommerceNotification").Elements("Order").Elements("OrderReferenceFields").Elements("ReferenceField") select el;  
            foreach (XElement el in de)  
                Console.WriteLine(el.Value);  
    

    And the following is my test.xml:

    <?xml version="1.0" standalone="yes"?>  
    <Upsscs SchemaVersion="1.0" applicationVersion="1.0.">  
    <Header>  
      <EcommerceNotification type="OrderCreatedNotification">  
        <Order number="26875690">  
         <OrderReferenceFields>  
            <ReferenceField id="1">79787709</ReferenceField>  
            <ReferenceField id="2">936N5D4CPU</ReferenceField>  
            <ReferenceField id="3"/>  
            <ReferenceField id="4"/>  
            <ReferenceField id="5"/>  
         </OrderReferenceFields>  
       </Order>  
      </EcommerceNotification>  
    </Header>  
    </Upsscs>  
    

    Here is also a related thread you can refer to.
    If the problem is still not resolved, please provide your code and xml file.
    Best Regards,
    Daniel Zhang
