IE & DOM - clanked

[chimpoid]

Hi there,


I have a minor problem with IE updating an i-frame withing a page.
It's straightforward enough. A hidden i-frame reloads and runs a php
script which downloads a listing from a MySQL databse and then cals a
javascript to transfer the content to another visible i-frame thus
preventing any reload flicker.


The code is as follows:

// Code
function insertusers(usersinput){
if(window.frames && window.frames["usersin"]) //IE 5 (Win/Mac),
Konqueror, Safari
aWindow = window.frames["usersin"];
else if(document.getElementById("us­ersin").contentWindow)
//IE
5.5+, Mozilla 0.9+, Opera
aWindow =
document.getElementById("users­in").contentWindow;
else //Moz < 0.9 (Netscape 6.0)
aWindow = document.getElementById("users­in");


if(aWindow.document) //Moz 0.9+, Konq, Safari, IE, Opera
aDocument = aWindow.document;
else //Moz < 0.9 (Netscape 6.0)
aDocument = aWindow.contentDocument;


var neweDiv = aDocument.createElement("DIV")­;
neweDiv.innerHTML = usersinput;
a = aDocument.getElementById("user­things")
b = aDocument.getElementById("newe­Div")
go = a.removeChild(b);

aDocument.getElementById("user­things").appendChild(neweDiv);


}
// End Code

The content works fine in mozilla and runs as expected dropping the
contents of usersinput (in the head of the function) as a child of the
div in 'a'.
In IE the error returned is: 'a' null or not an object
I have used alert to check that it is readin everything correctly as
far down as aDocument. I have also checked and the div userthings
exists and should be reading correctly but IE seems to balk at this and
kill the script.

Any thoughts would be most appreciated
