Welcome to the club.
You're not alone in your frustration. There are no good manuals. The "helpers" here don't work in the real world. I had the same problem today with the "Modify Existing Forms" PDF.
All I wanted to do was take my existing form, which I worked very hard to get just right, then add datepickers and do field validation. The *&^%$ goes wild and tries to validate every single field and totally messes up my form layout.
If I ask a question here I'll get an answer in a couple of days (I see it took them 4 days to get to you) but it won't be a real answer, it will be a question. Eventually, and indirectly, by their lame suggestions you'll finally figure it out for yourself or you'll go to hotscripts and find something that gets you close enough to what you thought you could accomplish in the first place.
They don't realize that we work on deadlines and we want to use their software to help us get things done faster. We don't have 4 to 6 days to figure out how to manually manipulate their buggy software.
