Javascript Errors

Hello All. I am developing a J2EE Application with quite a few javascripts. My problem is this...
They all work fine on my machine(running on the local server as well as a unix server), but when my manager tries to view the page he gets invalid object errors. I have made sure that all our internet explorer settings and version/service pack all match up. I also made sure we had the same JRE...

I guess my question is "Is there anything else that I should check to make them work?"

Thanks a lot for any help, we are supposed to go into production soon...HELP!

Make sure if you are using external js files that they are pointing to the server and not your harddrive. I have seen that....

Do you know what the errors are saying?
