OK, but unless this is just a learning exercise, why are you changing
code that works for code that does not yet work?  Using new Function and
then calling the resulting function is not any safer than calling eval,
if that is your reason.

Well something is probably wrong with the "new Function" call, but how
can anyone possibly help if you don't show the code?

This indicates a significant misunderstanding.  The result of the new
Function call is a function itself -- if it gets a name at all, it will
be because you store the result in variable.
