I have a client who needs to have guests complete various forms. They need to be able to take the information from one identical field from each form, by ID number, add them up and deliver the sum to a field on a document to be printed. ( I'm thinking forms, if there's another way to do it, that's cool)

Hopefully that makes sense. Can this be done? What would you charge me?

I have to have this done within 30 days <panic>. Please PM me if you can help.
