I'm building a simple one page (three fieldset: trip info, personal
info, payment info) online reservation form and need to create a
functional spec of the task flow. My question is about the consensus
concerning this or similar patterns. I'm wondering specifically, if
users generally desire or require a "please review your information"
before submitting your final order page or if that's just an extra
(unnecessary) step considering they're "reviewing" the information on
the form page as they're filling it our /and /that the form will have
built in error checking which will return a facsimile of the page with
incorrect field(s) highlighted.
