Create Target actors and submit button to check criteria

icete66

I am new to GameSalad and I have reached a dead end. My game concept is fully designed and I have created my actors, etc. However, the game requires players to move game pieces over blank targets. The game pieces/actors must match the requirements for the target or sequence of targets on each level when submit is pressed in order to reach the next level. How do I define the targets/actors so that after the player places them over the blank targets and clicks submit the game can verify if the correct pieces were placed in the correct targets and allow the player to move to the next level. Or, if incorrect, return them to the previous screen to try again?
