I get the error below when compiling my project. This error came about after I added two classes and used my project name as the namespace in these two classes. Any suggestions on how to resolve?

Value of type 'Report_For_Submission_Application._default' cannot be converted to 'ASP.default_aspx'. Type mismatch could be due to the mixing of a file reference with a project reference to assembly 'Report For Submission Application'. Try replacing the file reference to 'Report For Submission Application.dll' in project 'Report For Submission Application' with a project reference to 'Report For Submission Application'.    C:\Users\Whitney\Documents\Visual Studio 2013\Projects\ReportForSubmissionSystem\Report For Submission Application\Report For Submission Application\Search.aspx    1   1   Report For Submission Application
