You're missing a couple of usings.

Fire up the Visual Studio debugger to get more detailed exception messages.

which ones , i am getting all the intellisense using just ucommerce.runtime, have added @using UCommerce.EntitiesV2 , still no difference , and i am not getting any error messages in the debugger

I'm finding it difficult to figure out how the two scripts you posted related to each other. Are they both in the templete or is it just the last one?

I mean , i tried both one by one on the email template, but both comes up with the error , Also i have i have noticed, the error comes on the first line:

 var purchaseOrder =SiteContext.Current.OrderContext.GetBasket().PurchaseOrder;

If you attach the debugger and step over that line don't you get an error?

I am running the site live, cant use debugger , is it the issue with SiteContext.Current , the template is not able to get the basket , as i am using paypal and the email is send using the cehckout pipeline once the payment is done successfully. I have no knowledge of XSLT , but i also try to write an email XSLT and manage to get the guid of the order , but cant get any other values like email , below is the template :

xsl:stylesheet [

<xsl:stylesheet

  <xsl:param name="currentPage"/>
  <xsl:variable name="orderGuid" select="umbraco.library:RequestQueryString('orderNumber')"/>
  <xsl:variable name="Basket" select="CommerceLibrary:GetBasket()/purchaseOrder/@orderGuid"/>
  <xsl:variable name="cart" select="CommerceLibrary:GetPurchaseOrder($orderGuid)"/>
  <xsl:variable name="email" select="$cart/@emailAddress"/>
  <xsl:variable name="email1" select="$Basket/@emailAddress"/>

  <xsl:template match="/">

    

   

    <table>
      <tr>
        <td>

          <xsl:value-of select="$orderGuid"/>
        td>
        <td>

          
          <xsl:value-of select= "$email1" />
        td>
      tr>

Thanks for your assistance so far , any ideas of how to sort out the email issue .

I think there is a problem in checkout config pipeline , which is not passing the basket values

The checkout config is sending an email but without purchase order :

public class SendEmailTask : IPipelineTask<PurchaseOrder>

{

    public string EmailTypeName;

    public SendEmailTask(string emailTypeName);

    public PipelineExecutionResult Execute(PurchaseOrder purchaseOrder);

}

Once the checkout pipeline runs the SiteContext.OrderContext.GetBasket() is reset ready to start a new basket.

You'll want to use the querystring parameter orderGuid or orderNumber and load an order by CommerceLibrary:GetPurchaseOrder using that order number or guid.
