thank you for the quick response.
Here is what I want to accomplish. I have a form and I will send people to this form from various sources (Google Display Network, Facebook, Email, etc.). So, I want to refine a querystring on the links to this form that will denote the source. For example http://www.domain.com/form.aspx?source=GDN
The users comes to the form and fills it. On the data (on the CMS) I want to have a field called source that will have the value of the querystring. I guess I need a field on the Bizform. Should this be hidden on the live site? I guess it should. But how will it hold the data from the querystring? And how will I set its' value when I develop it?
Is it more clear now?
Any help is appreciated!
