What is your actual problem? By the way do you face that "problem" still?

Your first problem was exactly what the error message said, you can't return a value from a function if you are not in a function, where would it return it to?
I don't know what erreor message you are getting in the latest version but "string" is not defined in the code shown. You may want:

Code:

function removeBadCharacters(text) 
{
   if (text.replace) {
      return text.replace(/[<>\"\'%;\)\(&\+]/g, '');
   }
}
