[development] Form API and Javascript stuck

[ad4m]

Hi,

What drupal version are you using? You mmaight want to look at AHAH which is
made to work with dynamic forms. It is built-in in Drupal 6. Additionaly
there is an excellent AHAH Helper module, which extends functionality of
built-in AHA. You dont really need to write any js if the operations are
simple, like in your situation. Some usefull links:
