Everything works fine in all other browsers but in IE 8 it says that there is an error in line 128

Webpage error details

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; MDDC) Timestamp: Thu, 16 Sep 2010 02:33:35 UTC

Message: 'document.getElementById(...)' is null or not an object Line: 128 Char: 11 Code: 0 URI: http://tripleagent.co.uk/lerp.html

this is the line with the error. 

// 2.5.0 cannot auto update on ppc. Treat as broken.
                    else if (document.getElementById("UnityEmbed").GetPluginVersion() == "2.5.0f5" 
                        && navigator.platform == "MacPPC")
                        brokenUnity = true;

I am using Dreamweaver CS5 on windows 7 64 and the default html script that unity exports i just changed the background and added a few buttons. Do you know what the problem is?

That happens all the time. IMHO and in my experience, you can safely ignore the message.

Edit: It has to do with IE's implementation of the function, I believe. Here's a link for example.
