    Need Help posting value to iframe

    I would like to post the value of the combobox to the iframe below. Any suggestions?



    <form name="doublecombo">
    <p><select name="example" size="1" onChange="redirect(this.options.selectedIndex)">
    <option>Technology Sites</option>
    <option>News Sites</option>
    <option>Search Engines</option>
    </select>
    <select name="stage2" size="1">
    <option value="http://javascriptkit.com">JavaScript Kit</option>
    <option value="http://www.news.com">News.com</option>
    <option value="http://www.wired.com">Wired News</option>
    </select>
    <input type="button" name="test" value="Go!"
    onClick="go()">
    </p>

    <script>
    <!--

    var groups=document.doublecombo.example.options.length
    var group=new Array(groups)
    for (i=0; i<groups; i++)
    group[i]=new Array()

    group[0][0]=new Option("JavaScript Kit","http://javascriptkit.com")
    group[0][1]=new Option("News.com","http://www.news.com")
    group[0][2]=new Option("Wired News","http://www.wired.com")

    group[1][0]=new Option("CNN","http://www.cnn.com")
    group[1][1]=new Option("ABC News","http://www.abcnews.com")

    group[2][0]=new Option("Hotbot","http://www.hotbot.com")
    group[2][1]=new Option("Infoseek","http://www.infoseek.com")
    group[2][2]=new Option("Excite","http://www.excite.com")
    group[2][3]=new Option("Lycos","http://www.lycos.com")

    var temp=document.doublecombo.stage2

    function redirect(x){
    for (m=temp.options.length-1;m>0;m--)
    temp.options[m]=null
    for (i=0;i<group[x].length;i++){
    temp.options[i]=new Option(group[x][i].text,group[x][i].value)
    }
    temp.options[0].selected=true
    }

    function go(){
    location=temp.options[temp.selectedIndex].value
    }
    //-->
    </script>

    </form>
    <iframe frameborder="0" width="660" height="800" scrolling="no" name="myIFrame" src=""></iframe>

    Change this:
    Code:
    function go(){
    location=temp.options[temp.selectedIndex].value
    }
    to this:
    Code:
    function go(){
    self.frames['myIFRAME'].location.href=temp.options[temp.selectedIndex].value;
    }
