[cnixuser]

Hello, I am currently working on an ASP.NET web application. When I compile my code behind the page, I do not get any errors ;however, when I attempt to view my code in a browser I get the error that is the title of this post. I am going to include a copy of my code behind the page, and my .aspx file code, can anyone help me out here? I am using Visual Studio.NET 2003, and my code behind the page is written in C#.

Here is the error as it appears in my browser:

Any help that could be provided in this area, would be greatly appreciated.

I figured it out just now, I needed to remove the "get" statement in the C# code, and I needed to add "()" to "ImageURL" and "GetImageURL" in the code behind the page, and all of the databinding statments: < %ImageURL() %>
