First project. Do you know whats wrong with my code?

I have copied what it says in the book ive got with the arduino but... It doesnt seem to work, first it was something about ' void loop' not including something so I tried to remove some 'void loops' and now it looks like this:

int switchstate = 0;

void Setup () {
  pinMode (3,OUTPUT);
  pinMode (4,OUTPUT);
  pinMode (5,OUTPUT);
  pinMode (2,INPUT);
}


void loop() {
  // put your main code here, to run repeatedly:

switchState = digitalRead (2) ;

if (switchState == LOW) {

     digitalWrite(3, HIGH); //grön lampa
     digitalWrite(4, LOW); //röd lampa
     digitalWrite(5, LOW); //röd lampa

     else { 
  digitalWrite (3, LOW);
  digitalWrite (4, LOW);
  digitalWrite (5, HIGH);

  delay (250);
  digitalWrite (4, HIGH);
  digitalWrite (5, LOW);
  delay (250);
  

}

And now it says the 'switchState' isnt declared in the scope and highlighting the "switchState = digitalRead (2) M ;"

Can you think of anything that is wrong and if so, what and why? Arduino is really entertaining even thou i ran into issues already on the first project.

I want to learn more about arduino so i can control my led stripes in my van. Do you guys have any idea how an easy sketch may look like? If I wanted to change the colours by voice control. Say red and the light is red.

Hope I have made my self understood. Best regards

'switchState' was not declared in this scope

Where is switchState declared ?
switchstate is not the same as switchState

expected '}' at end of input

There are two }s missing at the end of the loop() function
Auto Format the code in the IDE and the problem should become apparent

... and by the way, Setup() is not the same as setup().
