"val" wasnt't declared in this scope"

i know this is a stupid question, but i'm new at Arduino: why does it give me the error "val wasn't declared in this scope"?

#define ledPin 13
#define inPin 7

void setup()
{
pinMode(ledPin, OUTPUT);
pinMode(inPin, INPUT);
int val = 0;
}

void loop()
{
val = digitalRead(inPin);

if (val == HIGH) {
digitalWrite(ledPin, HIGH);
}
else {
digitalWrite(ledPin, LOW);

}
}

You define val in setup so you can't see it in loop.
Put the definition in loop (best), or outside both functions (worse)
