searches and conditional results

[jagasker]

Hi,

I am trying to write a javascript on Windows XP for my website that is supposed to perform a text search on an external page and return a result which, based on the result, will play a certain audio file. The script that I am writing is not working, I keep on getting redirected to the external page in which I am trying to perform the search, and I am getting numerous javascript errors, such as 'member not found', 'body is null or not an object', 'expected ]', and 'expected ;'.
I have been trying to get this script to work all weekend, and it is getting frustrating. Any help to get this script functional would be greatly appriecated. 3 versions of the script are attached below.

All of the script versions have the wrong syntax. You need to load the page in a window, frame or iframe and then try to access it. However, since it's not from your domain, the browser will give a permission/access denied error. To work around that, load the site from your domain using some server-side code, or just code this on the server-side.
