You are storing the results in global scope, so any preceding function calls will cause the previously unnecessary values to accumulate.

You probably have invalid values in your return value? You can also use logging in all of the katas... Hope this helps you forward.

Your solution should be written inside the wordCounter function initially provided by the kata: is that what you did?

var wordCounter = function(text) {
  // TODO - Add your implementation here
};

Not sure. Which language are you using? And could you add backticks (`) before and after the test message itslf, just so I know exactly which part is being printed out?
