actionscript 3 - Where is that syntax error on line 2? -

ok, in next actionscript 3.0 code there syntax error on line 2, don't know is. i'm beginner please help me on this?

var numbertocast:number;

on next line there syntax error, says compiler, , haven't clue is

for (numbertocast = –1; numbertocast<2; numbertocast++){ trace("boolean(" + numbertocast +") " + boolean(numbertocast)); }

the problem - (numbertocast = –1;), it's not minus symbol. symptom of copying , pasting (out of microsoft office maybe? word bad replacing minus dash)

and per comment, need define (var) numbertocast (either prior loop or in loop declaration) or you'll different error after fixing minus.
