Dynamically fill selection tables



I am looking for a way to populate a table based upon the value picked from a previous table. For example "State" table includes state names; select Florida and the second table displays City Names; select City name (eg. Tampa) and get a 3rd table of Health clinics; etc. I want to only display 2nd or 3rd level details that are valid choices. I want to include all possible data values in the form (or on a web site for easy update) I would prefer not to use MS Access if possible. Adobe Livecycle v7, XP. Thanks in advance!
