Javascript & Google Maps error.

I'm fairly new to Javascript and it's more of a guessing game for me...
I'm trying to build an app for Google Maps and just had some issues recently.
First off I just wanted to say that everything works fine in FF and IE. It's Chrome I'm having issues with.
I understand that Chrome is still somewhat in beta stages, so some bugs might occur. However this seems like something I might have done.
I used a code that I found on Econym as a base and modified it slightly. Here is what I have:
Expand|Select|Wrap|Line Numbers
  1. <div>
  2.         <div id="search" align="center">
  3.             <table border="1">
  4.                 <tr>
  5.                     <td>
  6.                         <div id="map" style="width: 690px; height: 450px">
  7.                         </div>
  8.                     </td>
  9.                     <td width="250" valign="top" style="color: #4444ff;">
  10.                         <!-- =========== side_bar with scroll bar ================= -->
  11.                         <div id="side_bar" style="overflow: auto; height: 450px;">
  12.                         </div>
  13.                         <!-- ===================================================== -->
  14.                     </td>
  15.                 </tr>
  16.             </table>
  17.             <noscript>
  18.                 <b>JavaScript must be enabled in order for you to use Google Maps.</b> However,

  88. }
  89.             </script>
  91.         </div>

The error that Javascript debugger throws at me is:
"uncaught exception TypeError: Cannot call method 'getElementsByTagName' of undefined"
Any help would be appreciated!

I posted a dupe somehow...

I put the files online, so it might be a little easier to troubleshoot.
Here is the URL: http://nike1984.brinkster.net/Map.aspx
Thank you,

Looking at the page source, perhaps the problem is that the Google Maps code is included outside the head and there's no html tag.
Apr 7 '09 #4
That's correct acoder.
I just fixed the following problem by simply moving the first script link within the header section and also adding the doctype and validating the html.
Thank you so much!
