I am writing a quiz program in C# in Visual Studio. When I build it it doesn;t return an errors or warnings. However when I debug, it just brings up a blank screen with no text or buttons etc. I have tchecked all the names match those in the forms and tired changing the classes. Can anyone please tell me where I am going wrong? Many thanks.
