Forms Data Controls :: Display Picture In GridView

I had a problem before with GridView displaying picture and it was solve as post [URL] shows. I am trying to apply the same coding to another GridView with a different configuration and I am having a hard time making the adaptation. May someone take a look at it. What I am trying to add to this GridView is code as:

DataImageUrlFormatStringl='<%# IIF(System.IO.File.Exists(Server.MapPath(string.Format("~/UploadedImagesClassifieds/{0}{1}", Eval("AutoNumber"), "Pic1.jpg"))), string.Format("~/UploadedImagesClassifieds/{0}{1}", Eval("AutoNumber"), "Pic1.jpg"), "~/UploadedImagesClassifieds/NoPicture.gif")
%>'

And the GridView code is the following at the present time:

<
asp:GridView
ID="ClassifiedsDisplayGridView"
runat="server"
