Hello Everyone,
   I am trying to set a value in a input text element within an iframe.....
   let me use expert-exchange JavaScript topic area as an example...


<iframe id="objViewer" style="HEIGHT: 95%; LEFT: 17%; OVERFLOW: auto; POSITION: absolute; TOP: 5%; WIDTH: 85%"height="400" width="1000" scrolling="Yes" src="" frameborder="1"></iframe>

            <select name="selLink" style="width: 136px" onchange="sendInfo(this.options[this.selectedIndex].value)">
                    <option value="Ace">ACE</option>
                    <option value="Image View">Image View</option>
                    <option value="value test">Value Test</option>


      function sendInfo(dText)
            case "value test":
                //////////////////////////// What do i place here to be able to access the form in the iframe to set the value
                                                    say for example: Form(SearchForm)
                                                                             Input Text(query)

Try this:

frames['objViewer'].document.getElementById('query').value = 'the value of the query';

thns for the quick reponse...
I tried your suggestion and I got the following error message:

    Access is denied.
For browse security, cannot access the frame that in different domain, you will get "Permission Denied" when Scripting Across Frames (at least in IE).
