Hello Linda,
How many projects do you have in your solution? If you have more than one, you may find that when you try to compile, if one of the dependent projects doesn't compile successfully, you'll get these -- what I call "phantom errors." If you pay close attention to the output window when compiling, you can tell where the problems start and which project is really causing the error.
Hope that helps,

>That didn't help. I had already tried those but tried them again, just in case. I still get the same error. Any other ideas?
