Setting a value to a FreeTextBox in a Detailsview

Trying to set the FreeTextBox to a certain value. This is the code I use...

Dim FreeTextBox1 As TextBox =CType(DetailsView1.FindControl("'FreeTextBox1'"), TextBox)

FreeTextBox1.Text = ("Your document can be found <a href='" + nurl + "'>here.</a>")

It doesnt work. I get "Object reference not set to an instance of an object. "


Any ideas?

Thanks.
