Http Request Action - How to

I put the Http Request in the On Load Event (before Show HTML) an filled out all fields.

Enable: Yes
Request URL: 'http://mydomain.de/test.php' (in this file i wrote only a simple echo)
source: source_dropdown
target: target_dropdown
Request Event: onChange

now: i hoped when i change the source dropdown, the target_dropdown show me the echo from my test.php. But nothing is happened.

i cant see the onchange event in my developer tools in my Browser.

<div class="ccms_form_element cfdiv_select label_over" id="source_dropdown_container_div" style=""><label for="source_dropdown">Datum wählen</label><select size="1" id="source_dropdown" class="" title="" name="datetime_select">

						<option value="7">20. Dez 2013</option>
<option value="8">27. Dez 2013</option>
<option value="6">13. Dez 2013</option>
						</select>
<div title="" rel="tooltip" class="tooltipimg"><a href="#" onclick="return false;">?</a></div><div class="small-message">instructions</div><div class="clear"></div><div id="error-message-datetime_select"></div></div>

what i have to do that this Request work correctly?

Hi Systemcheck231982,

I've never used the HTTP Request action but my understanding is that it is to submit the form. It sounds as though you are trying to set up a double-drop-down where one dropdown is populated by the selection on another. Please see this FAQ

Hey Bob.
Youre right. I want a Dynamic dropdown. I know the FAQ You linked and i tried this but nothing is happened. I will Rey again and will Show You my debug Data.

Thx.
