Hi,
That means you're not successfully linking to the prototype.js file.
Double-check your script tag for Prototype and ensure that it's really
referring to the path you think it is. For things like this, the
script debuggers available from Microsoft (Visual Studio, and Script
Debugger) are useful and would probably show you that you have an
error in your script tag.
HTH,
