Hi there this error message keeps appearing when i try to calculate my data.

Answer 1

You're using FileSystem.WriteLine rather than Console.WriteLine.

See the difference here: https://msdn.microsoft.com/en-us/library/microsoft.visualbasic.filesystem.writeline(v=vs.110).aspx

https://msdn.microsoft.com/en-gb/library/system.console.writeline(v=vs.110).aspx
