Javascript from IFrame write to DIV in page

Can someone help me writing from an IFRAME to the div in my parent page. I am trying the code below, but I get a js error when it runs. I am guessing that if it is possible, the error is in the document.getElementById(id);. The script is in my IFRAME, and the DIV is in my parent page. Thanks in advanced for the help.

function writit(text,id)
{
      if (document.getElementById)
      {
            x = document.getElementById(id);
            x.innerHTML = '';
            x.innerHTML = text;
      }
      else if (document.all)
      {
            x = document.all[id];
            x.innerHTML = text;
      }
      else if (document.layers)
      {
            x = document.layers[id];
            text2 = '<P CLASS="testclass">' + text + '</P>';
            x.document.open();
            x.document.write(text2);
            x.document.close();
      }
}

Thanks for the quick response, I tried parent.getElementById, but didn't try parent.document. I'll give it a try tomorrow morning and let you know if it works. Thanks again.

I get the following error:

'x' is null or not an object

I just noticed that when I go put
window.parent.name, it gives me a layer within my iFrame. Is there a way to do like a top.getElementById or a way to find the outermost layer?

*sorry about the broken english in that last response, it was a series of copy/pastes gone wrong. I meant:

alert(window.parent.name);

gives me a layer within the iFrame.

you should try top.getElementById then.

No luck with the top.getElementById

I was wrong when I wrote:

//
alert(window.parent.name);
gives me a layer within the iFrame.
//

That is actually the name of my iFrame. I have tried the following code, but it didn't work either.

x = window.parent.parent.getElementById('Results');
alert(x.innerHTML);

x = window.parent.parent.document.getElementById('Results');
Gives - Access is denied error

Does that have anything to do with the embedded frame being on a different web server than the parent?

That is what I was afraid of. It looks like I may have to transfer my pages to the other web server to get it to work that way. That does make sense from a security standpoint. Thanks for the help!

Jayh99,

It seems like my comment above answered your question. The answer was you can't do it because the pages are on a different server. I'm a little surprised you said you didn't get an answer when your last comment seems to acknowledge it. I did provide information in that comment on why it wouldn't work but let me know if you still have a question. Let me know your thoughts on this.

@Netminder - How do we create links to a specific comment using just the new site (sans QP)? Just curious if you have a tip. :)
