    ajax drop/down list problem

    Hi Alex.
    The problem is that you define two variables (url) and (what) in the first <script>...</script> section, then you re-define them in the second <script>...</script> section, so the second definition will replace the first one because they are global variables.
    Please try this:

    <script>
    var url = "";
    var what = "";
    </script>
    <script>
    function GetStates(Country)
    {
    url = "country.php";
    what = "SetStates(req.responseText)";
    DoCallback("country="+Country);
    }
    function SetStates(States){...}[COLOR=Sienna]
    </script>
    <script>

    function GetCities(State)
    {
    url = "state.php";
    what = "SetCities(req.responseText)";
    DoCallback("state="+State);
    }
    function SetCities(Cities){...}
    </script>
