Pass value from parent to iframe dropdown box
<p>I need to pass a value from a parent to an iframe (on a different server, not in my control) and have the value make a selection in a dropdown in the iframe.</p>

<p>Example: mydomain.com/?agent=12345 (target will be the iframe)</p>

<p>In the iframed page, the dropdown has several choices, I need to have the value in the url be the selected the choice corresponding to the selection when the link is clicked and the page is loaded in the iframe.</p>

<p>Is passing in the URL possible or do I use JS, PHP? If JS or PHP, how?</p>

<p>Thanks.</p>
