You can do it with Javascript, assuming you don't need to "do" anything at
the sever with each new value (increased or decreased).
If that's the case then you should do it with Javascript, to spare a round
trip to the server just to modify a number in the user interface.
you can have something like this
...
<script language="javascript">
function increase() {
document.myForm.myID.value += 1;
}
function decrease() {
document.myForm.myID.value -= 1;
}
</script>
...
<INPUT type=text id="myID" value="1">
I think this might do the trick.
