  alert("hello");

Answer 1

That's because you've missed a closed curly bracket on the function calcEquation :) .

<script type=text/javascript>
        function calcEquation(){
          alert("hello");}
  </script>

Answer 2

  <script type=text/javascript>
        function calcEquation(){
          alert("hello");
  </script>

I think you forgot to close the function with } in the end.
