Posting value from query string into a hidden field

Hi - we have a Customer Portal/Site setup where we want students to give anonymous surveys of the different seminars. We want to send them a mail with a link to a form that automatically selects the seminar - where they can fill out the data. So - I want to pass the reference to a seminar in an url string - which should be really, really easy - but I just can't seem to figure it out. Below is my current code - what the hickory am I doing wrong?

 

 

<apex:page showHeader="false" standardController="Survey__c">
<script type="text/javascript"> 

document.getElementById('Seminar__c').value ='{!$CurrentPage.parameters.Seminar}';  
alert("What the heck !");
</script>
  <apex:stylesheet value="/dCSS/dStandard.css"/>

  <apex:composition template="{!$Site.Template}">
    <apex:define name="body">
      <apex:form >
      {!Survey__c.Seminar__c}
        <apex:pageBlock title="Please fill in this survey">
          <div class="field">
            <label class="formQuestion" for="">Seminar</label>
            <apex:inputHidden value="{!Survey__c.Seminar__c}" id="Seminar__c"/>
           <!--  <apex:inputField value="{!Survey__c.Seminar__c}"/> -->
           <!--   <input type="hidden" name="j_id0:SiteTemplate:j_id7:j_id8:j_id10" value="{!$CurrentPage.parameters.Seminar}"/> -->
          </div>
          {!$CurrentPage.parameters.Seminar__c}
          <apex:commandButton action="{!save}" value="Save Survey"/> 
        </apex:pageBlock>
      </apex:form>
    </apex:define>
  </apex:composition>
</apex:page>

Omg! Excuses for not finding this must be:
  1. I must have been very tired last Friday
  2. It was too easy
I can of course create my custom save action in the controller and get the query string parameter with ApexPages.currentPage().getParameters().get('Seminar')

Solved it myself!

Hi! I have a very quick question. How do you set your seminar parameter to be passed to you site?
 
My site is something like http://mysite.force.com/seminars  and I would like to pass a parameter. http://mysite.force.com/seminars?id=20394203489  doesn't work for me. Any ideas?
 
Thanks!
