Creating a pacman-like game, where a player eats objects. When a MovieClip (box) eats a circle on the stage, the score in the dynamic text field should go up by 10 points.
Receiving an error: line: `scoreField.text = " " + string(currentScore);
error message: Call to a possibly undefined method string.
