Change state of multiple objects
I'm trying to create an activity (Wheel of Fortune) where on the click of a buton - the corresponding letters will be revealed. I essentially have my base layer with the words and shapes above to hide the letters. At the bottom I have buttons (one for each letter of the alphabet). What I would like to do is that when I click a letter, all of the shapes hiding those letters will hide. I can get it to work on one letter but if there are multiple instances of a letter, only the first one is revealed. I've tried to group the shapes but the name of the group does not appear in my "change state of" menu.
