I want to save game and proceed.

Hi, I am making a game in which my player is getting gold by completing the scene + i want to save the game for each level so he can able to play other levels. But how to do it. I get the error when i use the save game attribute.
Thanks

Hey. I think it may be an idea if we could see how the save game block is being used.
Also, what would you like saved for the level?
Game attributes are your friend for this.

Yes i want to save the game attribute. Like completing each level the player gets the 50 coins and plus we is able to unlock the 2nd scene and still he can play the 1st scene.I want that game attribute to go persistent because player can also upgrade in the shop.
