Marcus -
  Definitely easiest way is to handle that in JavaScript. Somewhere in
your perl you will embed a few useful JavaScript functions to be
passed down on the completed page. But you cannot point the JavaScript
to the perl event; it just doesn't work that way.
  You can however use JavaScript to edit the page after it is already
loaded & rendered. So from here your questions are really JavaScript
questions, but here are a couple of pointers: you will need to make
use of the "onChange" event for your popump list, as you suspected,
but point it to a JavaScript function that uses (the magic beans...)
HTML DOM (via getElementby functions) and then actually editing
element contents with the innerHTML attribute.
