Movie clip detection in a game

I’m new to game construction, so bear with me. I’m creating a game in which the user gets three wrong answers, and the fourth wrong answer ends the game. Each wrong answer is shown as a child movie clip getting attached to a parent in one of 3 movie clips on the stage. When all 3 movie clips have child clips attached, and a 4th child clip tries to get attached, the game ends. Anybody know how to write a script for this? Do I need to identify a bunch of variables for this to work? Help! I’m blanking!

why don’t you just increment a variable?? like every time a person gets a wrong answer add 1 to a variable and if that variable equals three (if you start with the variable value at zero) then end the game.\r:) \rjeremy
