I am looking at this sample module:

http://api.drupal.org/api/file/developer/examples/page_example.module/5

but I am not getting it. The "A simple page callback." seems like it makes http://mysite.com/foo call the function page_example_foo() and so the user will see "The quick brown fox jumps over the lazy dog."

I tried adding this code to my Drupal 5.2 but it doesn't seem to work. Can you someone show me how I can setup such a thing? That http://mysite.com/foo returns the output which I determine from a function.

I don't actually need a menu item--I want the user to select an option in a dropdown and then submit a little form--based on their input I perform a search. What I can't figure out is how to get the search results to the browser.

Thanks!
