I have searched the forums for a couple days now to try and find out how to do this. I want to have a world select screen where you can buy the other worlds with coins. I have used the lock button to set up the button and have it set to use in game currency. I have the routing points set up as well. When I unlock the button with the coins, the lock icon disappears like it should but when I tap on the now unlocked button, it doesn't take me to the next world. What am I doing wrong?? (I should probably mention that the game was original set to "single world") Thank you for any help?
