Happens occasionally with Code Playground. You might want to post your code for inspection.

Some code needs to run though a program called a compliler so the computer understands it. Compilation error means the compliler has rejected the imputed code. Normally because of a syntax erorr ( syntax is the order In which parts of a statement should appear.)
