    While web site is running fine when i click the photos link i have an error "Object cannot be cast from DBNull to other types".

    in the page PhotoAlbum_List.aspx  line 11  " pages = Convert.ToInt32(e.Command.Parameters["@pageCount"].Value)"

    How can i fix this??

    This means that a value of type DBNull is returned (may be because you do not have any photos and the procedure is returning null).

    You can either use Int32.TryParse or check for DBNull before you do this. 

    // TryParse
    
    int count;
    bool result = Int32.TryParse(e.Command.Parameters["@pageCount"].Value.ToString(), out count);
    pages = count;
    
    // OR
    
    if(e.Command.Parameters["@pageCount"].Value != DBNull.Value)
    {
       pages = Convert.Int32(e.Command.Parameters["@pageCount"].Value);
    }

    I haven't used Club Site Starter Kit so I can only help with the error. Can you post the code around it, not just the exception statement?
