parent.frames[].document???

[gruetztian]

hi friends,

have a little question about javascript (working with frames access elements from frame to frame) and
why does this codebit didnt work??

var mytr = document.createElement("tr");
var mytd = document.createElement("td");
var mytext = document.createTextNode(message);

mytd.appendChild(mytext);
mytr.appendChild(mytd);

var a1 = parent.frames[0].document.open();
a1.getElementById("ausg").appendChild(mytr);
