Could someone tell me why My case Block is not showing in the Listbox.

Private Sub btnBill_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnBill.Click

        item = txtItem.Text
        duration = txtduration.Text

        Dim fmtstr As String = "{0, -15} {1, 17:c2}"
        '-----------------------------------------------------------------------------------------------
        lstResult2.Items.Add(" Receipt from Eddie's Equipment Rental")
        Select Case item.ToUpper & duration.ToUpper

            Case "1", "h"
                lstResult2.Items.Add(String.Format(fmtstr, "Rug cleaner", 16))
            Case "2", "h"
                lstResult2.Items.Add(String.Format(fmtstr, "Lawn mower", 12))
            Case "3", "h"
                lstResult2.Items.Add(String.Format(fmtstr, "Paint sprayer", 20))

Make a breakpoint at:
Select Case item.ToUpper & duration.ToUpper

Add to watch:
item.ToUpper & duration.ToUpper

what is the value of:
item.ToUpper & duration.ToUpper

analyze your select statement again or just use IF ELSE IF Statement...

Did it turn out to be the way you wrote the expression to test?

Select Case item.ToUpper & duration.ToUpper
             Case "1", "h"

The ampersand (&) will do a string concatenation; the ToUpper makes the text uppercase. Therefore, the case should be

Case "1H"
