Hmm. As there are three items ont the form that the user could change I
think i'll stick with the button as you suggest. It just doesn't look as
nice ... :(

not like this. e.g. if trying to enter "1234", that registers as 4
onChange events. You'd be better using onBlur, which is the event
triggered after this field loses focus. Although to be honest, that could
be annoying, especially if you're not finished editing the page. you might
just have clicked into the field, then clicked elsewhere to change
something else - the form would submit when you click outside of the box.
better to use a button to submit it - the drop-down select is better for
doing the automatic submission as it assumes you've made a change to the
field. it would also work with radio buttons, but not really any other
form fields.
you're better off keeping the javascript to a minimum and just letting the
user click a button when they're done.

OnChange?

Please respond to

Excellent!
Can the same be done for a texbox?
<input type="Text" name="Quantity#Replace(ItemIDPK,"-","_","ALL")#"
value="#Quantity#" align="RIGHT" size="3" onChange="submitForm()">
This would give an infinate number of possible quantities ...
