Help function for comments not working

Below is the script named ConeVol. After I saved the script and typed the statement of, help ConeVol, in the command window, I don't see the print out of the comments in %{ and %}. Can someone help me to understand why? Shouldn't help function print out all the help comments?

%{
      Computes volume of a cone.
      Creates variables radius and height.
      Result is assigned to variable volume and displayed.
      The script was written by Blaise Pascal
      on the year 1660
%}
radius = 3;  % Radius of circle at base of cone
height = 2;  % Height from base to point at top of cone
volume = (1/3) * pi * radius * radius * height    % Note: pi is built-in constant

Thank you, - Lisa

Replace all lines with begining % instead of %{ ...%}
