You can use Form.Observer to watch for changes to any values in a form. This
assumes you have assigned the name attribute to each of your form fields.
Without that, the getValue calls will return nothing. See
http://www.prototypejs.org/api/timedObserver/form-observer for more details.
Something a bit puzzling though is why your onchange is not working. If
using Event.observe(element,event,function), keep in mind that the names of
the events are "change", "click", "mouseover", . and not "onchange",
"onclick".
Event.observe(myButton,"click", function() {
alert("Leroy was here");
});
Or
myButton.onclick = function() {
alert("Leroy was here");
}

Subject: Re: [Proto-Scripty] Re: How to create math manipulatives
Well I am creating a small app. to help you understand what I am looking for
attaching a screen shot of my design. So basically as seen in the design
there are two sections in the right section you enter numbers and even a
slight change in that number must reflect in the answer.
In the left there again there are 2 compartments for tens and untits, tens
coulumn has 9 sub-columns and units has 9 sub-columns. Difference between
them will b in the images displayed in tens you will see a bunch of 10 of a
certain object(in each sub-column) whereas in units you will find only a
single object in each sub-column.
Now with a slight change in the right colums there should be an instant
change in the images displayed on the left.
I want an effect like shown by the onforminput event in HTML5. But somehow
this even aint working when I use it so I have to use onchange instead.
This does not help much because it eliminates the counting part from the
answer displayed which is very crucial.
Change from addition1.jpg screen to addition2.jpg screen needs to very quick

If you would care to give an indication of what it is that you need
help with, you are more likely to get that help. Is something not
working? (If so, what, and how?) Is there something you'd like to add
to it but don't know how to make it work? What?
