jquery_plugin_add not working

Hi Guys

This is now my second day struggling with this problem. I have web form which I have created with webforms module. I have created two markup fields:

1. head -> has jquery validation rules for form objects
2. html -> has html markup for fields etc.

Now i know i should be using the webforms fields but due to a long and complicated story I have set up my own fields using html and will handle the data processing in the additional processing section of the webform. My problem is this:

I am handling all validation using the jQuery plugin (validation) by specifying rules in the javascript (which i have added to the head markup field). The normal jQuery functionality is working great as field effects, hiding etc are working but i cannot get the validation to work. I have tried adding the validation file using jquery_plugins module in the page.tpl.php file, template.php file (as per other answers on the forum) but i get nothing. Every time I click that button it just posts the form without any validation. The only two things i can think of is either the form name which is not being referenced correctly E.g.

$("#webform-client-form-2324").validate({
rules: { ... }
});

or drupal is not seeing the javascript plugin file for the jQuery validation plugin E.g.

jquery_plugin_add('validate'); print $scripts;

If i view the page source for the form the only javascript file i see referenced is this:

script type="text/javascript" src="/fsp6/sites/default/files/js/0d8c43b8f264eb1633332e5f58105492.js">

Any help would be greatly appreciated.
