WebUserControl is ambiguous in asp.net vb

I am building an asp.net vb website, and having troubles with webusercontrols.  I have several user controls: menu_top1.ascx & menu_top2.ascx & menu_aboutus.ascx.  I have several pages created that reference these controls.  I can view the pages, and look at them one at a time, however, when I publish the site through Visual Studio 2008, I begin getting errors "aa_includes_WebUserControl' is ambiguous" at each line where I reference the  user control I want to use.  I have included two web pages where I have used the webusercontrols and the .ascx files.  Thanks for the help.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Your menu_top2.ascx and menu_aboutus.ascx both have the same classname (aa_includes_WebUserControl) they must be different.
