Help Detecting Real Player in a Browser

I found a handy little script that performs plugin detection within IE and Netscape.  It seems simple enough but I cannot get it to work.  It just doesn't return anything.

The script can be found here:

http://www.javascriptkit.com/script/script2/plugindetect.shtml

The page I included it on for testing purposes can be found here:

http://www.wbspenguins.com/video/detect.asp

The plugin.js file is located:

http://www.wbspenguins.com/video/plugins.js


Any help is appreciated as I am sure its a two minute fix for the more knowledgeable

I tried that script but am getting the follwoing error:

Active Server Pages error 'ASP 0138'

Nested Script Block

/video/detect2.asp, line 20

A script block cannot be placed inside another script block.


This is where I start to fall apart when it comes to coding.

I see.
That script create VBScript (it write script into document) in ASP page.
ASP page also uses VBScript.
so try to replace 20 line with: document.writeln('<script>');
