We've been using Zoho Creator for about 12 months and need some customisation done to streamline things a little. I've done the basics, but need some help doing the following: - creating an invoice - creating a booking form (same type of info. as the invoice) - doing conditional lookups - 2 way flow of data on some forms - Using sub forms correctly. I've attached a little diagram that explains the overall system (it's not big, I just want it streamlined), and I'm after some quotes for assistance. Thanks :).
