Average?

hi all does someone know how to work an average out....using a list box...its getting me confused...it needs to work out the total of all the numbers entered and divide by itself....

thanks

little_boy,
assuming your last post example, something like this

Code:

---

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim i As Integer
        Dim d As Double
        d = 0
        For i = 0 To ListBox1.Items.Count - 1
            If CDbl(ListBox1.Items(i)) >= CDbl(TextBox1.Text) AndAlso CDbl(ListBox1.Items(i)) <= CDbl(TextBox2.Text) Then
                ListBox2.Items.Add(ListBox1.Items(i))
                d += CDbl(ListBox1.Items(i))
            End If
        Next i
        ListBox2.Items.Add("Average: " + CStr(d / ListBox2.Items.Count))

End Sub
