title: Label text remains unchanged
body: <p>So I'm deliberately trying to make a Download ETA Calculator using Visual Basic 2013 Ultimate.. but after 3 hours of work, I tried running it but it won't show the final result (The Estimated Time). I am also asking you how to convert the result into Time format..
  here is the code</p>
  
  <pre><code>Public Class Form1
  
  Private Property z As Object
  
  Private Sub Label1_Click(sender As Object, e As EventArgs)
  
  End Sub
  
  Private Sub Button2_Click(sender As Object, e As EventArgs)
  
  End Sub
  
  Private Sub LinkLabel1_LinkClicked(sender As Object, e As 
              LinkLabelLinkClickedEventArgs) Handles LinkLabel1.LinkClicked
      Process.Start("www.speedtest.net")
  End Sub
  
  Private Sub Button1_Click(sender As Object, e As EventArgs) 
                            Handles Button1.Click
      Dim x, y, z, a As Integer
      Dim sum
  
      x = TextBox1.Text
      y = TextBox2.Text
      sum = Label1
  
      If RadioButton1.Checked = True And RadioButton3.Checked = True Then
          z = x / 1024 / y
          a = z / 60
          sum = a / 60
      End If
  
      If RadioButton1.Checked = True And RadioButton4.Checked = True Then
          z = x / 1024 / y
          a = z / 60 * 1024
          sum = a / 60
      End If
      If RadioButton2.Checked = True And RadioButton3.Checked = True Then
          z = x / 1048576 / y
          a = z / 60
          sum = a / 60
      End If
      If RadioButton2.Checked = True And RadioButton4.Checked = True Then
          z = x / 1048576 / y
          a = z / 60 * 1024
          sum = a / 60
      End If
  End Sub
  
  Private Sub RadioButton1_CheckedChanged(sender As Object, e As EventArgs) 
                                          Handles                                                  
                                          RadioButton1.CheckedChanged
  
  End Sub
  End Class
