 * I am by no means a programmer and have added many plugins to my WordPress installation.
 * When I view my site using Internet Explorer, I receive a script error on the 
   page (which does not say much I might add):
    ` Line: 83 Char: 2 Error: 'null'
   is null or not an object Code: 0 URL: http://test.spirko.net/vw
 * The strange thing is I do not receive this error using FireFox. I understand 
   this is not that much information, but I really could use anybody’s help.

 * I would search the Microsoft forums. I did see some references when I did a google
   search on that error. Can you identify your plugins that use javascript?
    Maybe
   also try a hard refresh (Ctrl-F5) to see if the error goes away.
 * I have the same IE version and don’t get that error when I go to your site.

 * Thanks, I will try that. I just did’t know where to start since this is such 
   a generic error.
 * One good thing is it doesn’t seem to be affecting anything.

 * You guys need to dump IE and get a more developer friendly browser.
 * your error is in `livepreview.js` and thus, the livepreview plugin:
 * `var commentArea = document.getElementById('comment'); 
    commentArea.onkeyup 
   = function(){
 * `commentArea` is null because there is no comment form element.
 * You can fix it by just adding a :
 * `if (commentArea != null) {
    commentArea.onkeyup = function(){ ... } }
 * Oh, and don’t forget to tell the plugin developer about the issue.

 * Edit: hadn’t yet seen the immediately prior post before posting this;
    —————————-
 * On your site I get the following error in Firefox:
 * “Error: commentArea has no properties
    Source File: [http://test.spirko.net/vw/wp-content/plugins/livepreview.js](http://test.spirko.net/vw/wp-content/plugins/livepreview.js)
   Line: 82″
 * The JavaScript is looking for something with id of “comment” and not finding 
   it.

 * I use the same plugin as jspirko and I get the same error message in IE. I tried
   VaamYob’s fix (even copying jspirko’s modified script directly), but to no avail.
   The error is reproduced on two different blogs with different setups.
