Save attribute not working

raciukas22

I create a game for kids. One of the fearures is that everytime they complete a task they get stickers. In the stickers' page all sticker images has alpha set to 0, once task is completed it should change to alpha 1. And i want to save it so they do not become invisable again. Because everytime task is completed I change integer to 0 so tasks can be played again. Many thanks who could help me.
