Default Passing value to new window

I'm new to Javascript and I want to pass values from my window to a new window. The new window was not programmed by me and it is already on the Web, so I cannot add/edit the code content of the Web page. The codes that I have on my window are below:

Code:
<script>
    var NewWindow
        function openNewWindow() {
            NewWindow = window.open("http://www.webexample.com","NEW","resizable=yes");
                }
</script>
My window's form is called "Form1" and the child window's form is called "EditForm". I have an ASP textbox called "Value" that I want to pass to the child window's textbox called "ValueDisplay" (Not an ASP textbox but an input type=text tag). The following codes is from the parent window to pass my value to the child's window value.

Code:
<script>
    function test() {
        NewWindow.opener.NewWindow.EditForm.ValueDisplay.value = document.getElementById("Value").value;
    }
</script>
I keep get an access denied or permission denied error statement when I click the error message in the status bar.

By default you can't communicate across windows from different domains. You maybe able to change the settings in the security section for the zone the page is in, "Allow data source access across domains", but I've had mixed results in the past with this and it would mean changing all the users' settings who ran the page.
The restriction is in place to stop unwanted access to another page, e.g you are logged onto your bank account as well as a phishing site at the same time.
