I am working on a web app and trying to code a form with two dropdown lists. The list in the second dropdown will be dependent on the selection from the first one. The task itself isn’t too complicated except that once the first selection is made, I need to make a database call to pull the data for the second dropdown. This is where I am having difficulty. Both lists are in fact populated from a database. I am working on this in a python script and have been trying to do this w/ an onChange javascript function. The web app is built in Zope and page templates may be an option along w/ the python scripts.
