IE errors that most people aren't seeing

Hi, I am new to web design and have tried to get help but no one seems to be able to reproduce the error and or fix it. All of my pages except index.php load but have the following error message in IE8. I have tried on probably 10 different computers (all from different IP addresses and varying in age and operating system (XP, Vista, 7). I always get the error message but other people in other countries usually cannot reproduce the error.

My site is www.distinctbuild.ca

and the error message I get is:

Webpage error details

Message: Object doesn't support this property or method

Code: 0

I also have a strange issue with my footer. I have one footer template that I use on every page. For some reason it works everywhere EXCEPT index.php where it is not centered and adds an "A" with an accent in front of the copyright symbol. Any ideas what is wrong with the code here???

Thank you SO much for taking a look!!!! I really appreciate it!
