If All Candles Inactive, Fade To Black Script?

[FurtherGames]

Hello, again!

Is there a script so that if, for example, there are three candles in a room. To blow them out the player must collide with the script area surrounding that candle. Basically, when the player collides with the area it renders the candle inactive. Is there a way so that once all candles are inactive the screen fades to black? Like this:

Walks over to Candle 1 Area - Blows the candle out
Candle2&3 still active, so no Fade To Black

Walks over to Candle 2 Area - Blows the candle out
Candle3 still active, so no Fade To Black

Walks over to Candle 3 Area - Blows the candle out
All candles inactive, fade to black occurs

Also, would it matter if the player did blew the candles out in a random order?
