[ ... definitions of "argument" elided ... ]

| argumentative:
| 1. given to arguing; contentious
| 2. characterized by argument; controversial

His answers were simply helpful explanations of what was wrong in the
code under question.  Except for his summary, nothing attacked the OP
or tried to refute other points of view.

I always pick useful things up from your posts. Pls don't stop them.

Just a "me too".
Once one has learned to survive his "poetry" by gnawing one's own legs 
off, his contributions can be quite useful and instructive.
I always read them.

Yeah, and PE does *not* say things like "poorly written code was good 
enough for my great grandfather so its good enough for me" ;-)

     I walk an hour most days for cardio.  I need my legs.  YMMV, and
will, if you have no legs and I do.

Thank to all that posted for your help.

1) The reason for only posting code snippets was that form does
calculation of someone else's equations which I could not share.

2) This is fully functional and working but used method which were not
generalized. That was the reason for the inquiry

This is what I have now.

function numeric( field, fallback, name ) {
     var num = parseFloat(field);
     if (isNaN(field)) {
         alert(name + " is not numeric");
         return fallback;
     } else
         return num;
}

<TR><TD ALIGN="RIGHT">
<b>Valve Diameter in Millimetres </b>
</TD><TD>
<INPUT TYPE="text" NAME="VD" SIZE=7  onChange="AInput =
numeric(this.value, AInput, 'Valve Diameter')">
</TD></TR>

When I have more time I will look into implementing what Stefan
suggested about replacing the "isNaN"

Thanks again,

Stan

Easily :
  You are not saying which browser you have been using.
  You have not posted complete working/failing code.
  You have not reported the output (including "none") of the browser's
    native, or another, debugger.
  You've not remembered things said in the newsgroup FAQ.
  You've not said exactly what you expect, nor what you get - that code
    works as it should, only your expectations were wrong.
  And, as a minor detail, your code is wrong.

To convert a typed input String to a Number, unary + is commonly best;
neither too liberal nor too rigorous.  For example, AInput = +field .
Then check that the value of AInput is admissible.

                                And, posting from -0400, should you
                                be spelling Millimetres correctly ?

There are a few word spelled that way since the original code was
written by someone in
the UK. I am changing the User Interface. Here in the US I would have
used inches. <g> I mean "Atmospheric Pressure Reading in Millibars" or
"Vapour Pressure" <lol>
