BCE0022: Cannot convert 'String' to 'int'.

HI, I’m new with unity. I’m trying to practice but i’m getting this error BCE0022: Cannot convert ‘String’ to ‘int’ with this:
can someone help me please?

var score: int = “500”;

var personnage: String = “Jean”;

var estArme : boolean = false;

print(“Le score de " + personnage + " vaut " + score + " et il est arme” + estArme);

int = “500”

should be

int = 500

placing something in parathensis means its a string

typing var score : int
means score is an int

cannot convert string to int.
