Add ajax address verification to Drupal form

I'm using Webform module in Drupal working and a separate test address validation form using a address validation service using AJAX to display results. I need to have the code from the test address validation form modified to work with the working Drupal webform. Drupal webform has has two address groups, each need a "Verify Address" link that: - takes data from address fields and submits to address verification service via AJAX - displays verification results within DIV next for address group - results contain link to replace address fields with corrected address via javascript I think it should be pretty simple for those of you who know AJAX well.
