Your RecnumToModify radio button does not have a VALUE attribute, but
instead has a rather elaborate ACCESSKEY attribute. While there is no
value there is no potential for passing it.

At all Rob's markup is broken. He should move input element with name
attribute "RecnumToModify" as child of form element.

Never do that, older IE will mangle the name/valie of a submit, use a
hidden valure.

var recnumtomodify = Request.form("RecnumToModify");

Depending on the possible range of values here, there should probably
be some 'escaping' for attribute value context.

Do you mean (by "that") name the INPUT element "submit"? That will
make the form's - submit - method inaccessible, but on many more
browsers than just IE (older or otherwise), but is only really
significant if the intention is then to attempt to use the form's -
submit - method (even if it does represent a bad habit that is best
avoided in general).

As Asen Bozhilov pointed out yesterday, if the INPUT filed is not
contained within the FORM element then it is not part of the form and
its VALUE (now that it has one) will not be submitted with the form.

Yes. Would be particularly bad if the value contains a double quote. :)

The method is Server.HTMLEncode:-

Yes and no, I mean do not try to send the value of the submit button, as
some older browsers seem to make a mess of that. Since it is near
impossible to test for all versions of all browsers:

I have never seen an issue with <input type="submit"> that would justify
this assertion. Are you confusing this with <button type="submit">,
which certainly is inconsistent across browsers (particularly with
regard to the values submitted)?

You could very well be right,
perhaps even with a "untyped" <button>
