however I still am unable to compile  the code-behind  page. I tried the 4 following combinations: removing the Src & removing the Inherits tags from both aspx  directives, keeping the Src directives in both & removing the Inherits from both, removing the Src directives in both & keeping the Inhertis directives in both, and of course (the original scenario) having both Src & Inherits directives in both. I still get the error  "E:\archive\BB\default.aspx.cs(250): The namespace 'BB' already contains a definition  for 'BBList'" every time...
