****pping,tax information in the Basket

I want to display the ****pping, tax handling and grand total information in

the Basket. I could display upto Sub Total. After that every thing is 
appearing $0.00.

Firtly I have tried to include all the ****pping information

Then I have run the Basket and total pipelines as follows

pipeInfo = New PipelineInfo("Basket")
pipeInfo("CacheName") = "discounts"
pipeInfo.Profiles.Add("User", CommerceContext.Current.UserProfile)
Basket.RunPipeline(pipeInfo)
pipeInfo = New PipelineInfo("Total")
Basket.RunPipeline(pipeInfo)

Then I tried to get the following information from the Basket form

           ****ppingTotal = 
CType(txContext.CartOrderForm.****ppingTotal.ToString(), Decimal)
            If Not (IsDBNull(****ppingTotal)) Then
                ****ppingTotalTextLbl.Text = (****ppingTotal).ToString("C")
            End If
            taxTotal = CType(txContext.CartOrderForm.TaxTotal.ToString(), 
Decimal)
            If Not (IsDBNull(taxTotal)) Then
                taxTotalTextLbl.Text = (taxTotal).ToString("C") 
            End If
            Total = CType(txContext.CartOrderForm.Total.ToString(),
Decimal)
            If Not (IsDBNull(Total)) Then
                CartTotalTextLbl.Text = (Total).ToString("C")
            End If

I am getting error in the total pipeline due to which I am not getting any

****pping, tax or other information.

I need some definite solution to show my ****pping information in my
Basket. 
Actually I want to implement Order-Level discount like Free ****iping. In
such 
a case ****pping value would be $0.00, while in any other case it should
show 
somw value.
