Here is my code:

Servo myservo;

#define in4 6 //Motor2 L298 Pin in1
#define enB 5 //Enable2 L298 Pin enB

#define R_S A0 //ir sensor Right
#define L_S A1 //ir sensor Left

int pos = 0;

void setup() {
pinMode(A0, INPUT_PULLUP); // Soil Moisture Sensor 1 PIN A0
pinMode(A1, INPUT_PULLUP); // Soil Moisture Sensor 1 PIN A1
pinMode(8,OUTPUT); // Relay Module PIN D8

digitalWrite(8, HIGH);

pinMode(R_S, INPUT); // declare if sensor as input

analogWrite(enA, 150); // Write The Duty Cycle 0 to 255 Enable Pin A for Motor1 Speed

}

void loop() {

Please help fast im on a deadline for a project

Perhaps you are. But, none of the folks on the forum who might help you for FREE are. So perhaps you should consider rephrasing your request.

You have code outside of a function.

Every { needs have } and hopefully in the correct place.

Which function is that code in?

What they do in you're main loop? Functions and procedures must outside the setup and loop scope.
