// 
//  9/13/07 VS for /employer/createad/index 
//  1. fields wont be loaded from another employer account
//	2. text fields will not be overwritten if already there from db
//  3. saves all form fields in one cookie, ad body in up to 2 cookies
//  4. saves fields: joblocation to autonotify 
//	5. cookies expire after 30 days or when next step is clicked
//  6. category cannot be saved at this time because the checkboxes have the same name
//
// ------------------------------------------------
// This function will concatentate all the fields in	
// in the form into one string, delimited by a PIPE
// symbol, into one cookie. The cookie name is the 
// same name as the form name. ALL fields are saved.
