Field value from custom object inside visualforce page

I have a custom object called Placement that has a custom field in it called URL.

I also created a visualforce page that displays an iframe. This page is displayed in my Portal as a child. I need to take the custom field, URL, from my parent object and display it as the src in my visualforce page.

<apex:page StandardController="Placement__c" sidebar="false">
<apex:iframe src="{!URL}"/>
</apex:page>

This is not working.
