SSIS Project, Adding to ASP.net Application

I need to add an SSIS project to an application. The goal is that it allows the user to Import records into the application. I get "The connection name 'SalesConnectionString' was not found in the applications configuration or the connection string is empty" when I try to view the Import UI pages in the browser. So, I suppose it’s not referencing the connection in the application web config file. What do I need to modify so that the import project can be integrated with the application so the user can select Import from the menu an process the importing of records? The import project code is attached. ## Deliverables Answer to the question above or direction to solve the issue. ## Platform Visual Studio 2005 Visual Web Developer 2005 SQL Server 2005
