Change from a Page to an I frame

P: 1
I have an iFrame declaired like that::
Expand|Select|Wrap|Line Numbers
  1. <iframe id="iFrame" runat="server"  class="tablecolumndiv" ></strong>
I put the two lines:
Expand|Select|Wrap|Line Numbers
  1. Protected WithEvents iFrame As System.Web.UI.HtmlControls.HtmlGenericControl<br/>
  2.     Public frame1 As HtmlControl = CType(Me.FindControl("iFrame"), HtmlControl)
  3.  
In my code behind.
But when I come to the:
Expand|Select|Wrap|Line Numbers
  1. frame1.Attributes("src") = "/Pages/Support/Asp/Help01.aspx"
It throws me an error of :
Object reference not set to an instance of an object.
Because the
Expand|Select|Wrap|Line Numbers
  1. Me.FindControl("iFrame")
has a value of nothing
That error eliminates when I delete the `runat` from the element.
Why?
