Saying it's not declared! HELP!

HELP! I don't know how to do this, because I believe I have declared " leftMotorDirection ", but Arduino is saying I'm not. Please help and tell me what I can do. I'm just now starting this. Is what I did right?

define rightMotorSpeed 10

define rightMotorDirection 8

define leftMotorSpeed 9

define leftMororDirection 4

void setup() { // put your setup code here, to run once: Serial.begin (9600); pinMode (rightMotorSpeed, OUTPUT); pinMode (rightMotorDirection, OUTPUT); pinMode (leftMotorSpeed. OUTPUT); pinMode (leftMotorDirection, OUTPUT); delay (1000); }

void loop() { // put your main code here, to run repeatedly: digitalWrite (rightMotorDirection, LOW); analogWrite (rightMotorSpeed, 255); digitalWrite (leftMotorDirection, HIGH); //this is where it says I haven't declared leftMotorSpeed analogWrite (leftMotorSpeed, 255);

}

Its not lying. Its really not declared, because you spelled it wrong.

define left*Moror*Direction 4

Oh my :confused: Sorry. Thanks!
