title: Error in VB.NET code: "Argument not specified for parameter"
body: <p>When I place <code>Set_Symbol()</code> in my code it give me two errors.</p>
  <p>Errors:</p>
  <blockquote>
  <p>Argument not specified for parameter 'e' of 'Private Sub Set_Symbol(sender As Object, e As System.EventArgs)'.    d:\documents\visual studio 2010\Projects\Math Game\Math Game\frmindex.vb</p>
  <p>Argument not specified for parameter 'sender' of 'Private Sub Set_Symbol(sender As Object, e As System.EventArgs)'.   d:\documents\visual studio 2010\Projects\Math Game\Math Game\frmindex.vb</p>
  </blockquote>
  <p>This is what Set_Symbol is:</p>
  <pre><code>Private Sub Set_Symbol(ByVal sender As System.Object, ByVal e As System.EventArgs) _
      Handles rbnaddition.Click, rbnsubtraction.Click, rbnmultiplication.Click, rbndivision.Click
          Dim rbn As RadioButton
          rbn = CType(sender, RadioButton)
          symbol = rbn.Tag
      End Sub
  </code></pre>
  <p>This is how I called it:</p>
  <pre><code>Private Sub frmindex_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
      symbolrbn(0) = rbnaddition
      symbolrbn(1) = rbnsubtraction
      symbolrbn(2) = rbnmultiplication
      symbolrbn(3) = rbndivision
      Set_Symbol()
      Populate()
  End Sub
  </code></pre>
  <p>Why is it throwing this error?</p>
