Token does not exist error

In a dropdownlist I have the following code in the
SelectedIndexChanged event:

If Dropdownlist2.SelectedItem.Text = "Chick Tracts" Then
System.Diagnostics.Process.Start("http://www.chick.com/")
End If

But...when I make the selection I get the following error:
"An attempt was made to reference a token that does not exist"

Can you tell me what's wrong?

Thanks

I was trying to pull up a different URL than my own, and was successful by changing my code, like so: Response.Redirect("someURL")

But...that replaced my URL window with the new one, which I didn't want to do. I wanted a new window to be created in addition to my own, and discovered it had to be done with javascript in a .Write statement, as opposed to a .Redirect statement, like so:

Response.Write("<script language = javascript> Window.Open ('someURL', '_new') </script>")
