No and no.

That was actually one of Thomas's more useful replies. Nobody here would
have been surprised if he had answered your question "Can anyone see
what I am doing wrong?" with "Yes" and no further comment. At least you
didn't give him a chance to say "There is no javascript".

Manners aside, most of his points are valid. Especially: don't use
eval() unless you know exactly what you are doing; do validate the
document before you begin debugging your scripts; stanForm.VD is not a
good way to reference a form element; and don't expect an assignment to
a function parameter to be visible outside the function. These points
really are important for you to understand. The rest will come with time
and practice.
