APEX

Hi -- I have some javascript called in a Page 0 region rendered after the header. It works
fine in Firefox, but not in IE 8. The json source is on the server:
<script LANGUAGE = "JavaScript" src="#IMAGE_PREFIX#javascript/json.js"></script>

The error:

Errors on this webpage might cause it to work incorrectly.

'JSON' is undefined
json.js
Code 0
URL: http /localhost:7777/i/javascript/json.js
Line: 199 Char: 1

Then another entry, simply:
'JSON' is undefined
json.js
Line: 199

The javascript code doesn't execute. (Note, it didn't execute in IE 7 either...)

The error links to the following line in json.js:

JSON = JSON || {};

Any ideas? I'm not nearly familiar enough with json or javascript to know what's
going on here...

Thanks,
Carol
