Re: VuGen - save the value of hidden input in HTTP response

web_reg_save_param parses raw HTML of the page returned from web server. So the concept of "hidden field" for web_reg_save_param is not relevant. If it doesn't work for you (but you are 100% sure that web server returns the value you want to capture) most likely you didn't place web_reg_save_param in the right place within your script.
