I've designed a form (in InfoPath 2003) that has a repeater section with my
data. Right now as the user continues to 'insert item' it gets added to the
bottom of the file (or wherever they choose to place it). I'd rather have a
form which shows 1 item at a time, and has buttons to browse between to the
prev or next item, and a button to insert a new one. How do I do this? Some
pointers to tutorials or sections of the help should be enough to get me
going.

Also, can one set up unique type constraints, where a certain field has to
be unique for each repeated item.

Thanks!
