[Javascript] Is Numeric Function

[flavio]

  Well.. about the question I'm also not so sure if is that what you want, but 
I believe you need the function to "return true" is the string is empty, right?
(or not?? LOL)

  If is that it you just have to change the
> if(passedVal == "")
> 	{return false;}
  to
> if(passedVal == "")
> 	{return true;}

 Hope to help
