Puzzles on chesskid iPhone app

Hello..

I just got 2 memberships for my kids on chesskid, and downloaded the chesskid app.. I was thinking this was going to be great - until I saw the puzzles.. they look like great tactics puzzles, but there's no feedback as to weather or not the moves entered are correct or not, and when you solve the puzzle - nothing happens..

is there something wrong, or is that just how you designed it?

Hi all - Problem solved.. I noticed an update available on itunes - which is weird because I only downloaded the app a few days ago so when I downloaded it the first time, I didn' get the latest rev... No big deal though - the updated rev has all of the functionality and is pretty slick.. My 9 and 7 year olds like it anyway!
