Please 'd like to create a customized hidden field in a zoho webform (lead) to push a url parameter (string such as keyword = www.mywebsite.com?keyword=value) in a hidden field  .

i follow this tutorial :  http://crmkbase.zoho.com/how-to-track-the-source-of-the-leads , but i realize that the hidden fields labels suggested are not the one i 'd like..In fact, .i d like a customized label (keyword) which match the url parameter ..

Any help appreciated..
