My son is playing on the ipad, in Campaign he has completed the 9th stage "school" and received a total of 15 out of 27 stars, and now wishes to open the 2nd screen. It says he needs 5 stars, but has 15 so do not understand why it will not open. Or do you need 20 stars and it is telling him to get 5 more??
