header tag addon doesn't work

[fubu]

How does everyone get it to work? I've been trying to install header tag addon v2. So far I've been getting the following messages:

 

Notice: Use of undefined constant DIR_WS_FUNCTIONS - assumed 'DIR_WS_FUNCTIONS' in C:Program FilesAbyss Web Serverhtdocscatalogincludesapplication_top.php on line 14

 

Warning: main(DIR_WS_FUNCTIONSheader_tags.php) [function.main]: failed to create stream: No such file or directory in C:Program FilesAbyss Web Serverhtdocscatalogincludesapplication_top.php on line 14

 

Fatal error: main() [function.main]: Failed opening required 'DIR_WS_FUNCTIONSheader_tags.php' (include_path='.;c:php4pear') in C:Program FilesAbyss Web Serverhtdocscatalogincludesapplication_top.php on line 14

 

I've pasted as per Linda's instructions (in application_top.php):

// BOF: WebMakers.com Added: Header Tags Controller v1.0

require(DIR_WS_FUNCTIONS . 'header_tags.php');

// Clean out HTML comments from ALT tags etc.

require(DIR_WS_FUNCTIONS . 'clean_html_comments.php');

// Also used by: WebMakers.com Added: FREE-CALL FOR PRICE

// EOF: WebMakers.com Added: Header Tags Controller v1.0

 

Very confused! Please help.
