Arduino Football Table Project

Hello there,

i am currently doing my work for my school exams.
I want to build an sensor that makes an sound when the ball rolls over the gate.
I replaced the sensors with buttons. My teacher said it does the same.
The first button works but the second is not working.
I tried to add something to the programm so that it says here is another button.
Here is the code and the error message. :

code:

int LEDblau=6;
int taster=7;
int tasterstatus=0;
int links=8;
int rechts=9;
int taster2=4;
void setup()
{
pinMode(LEDblau, OUTPUT);
pinMode(taster, INPUT);
pinMode(links, INPUT);
pinMode(rechts, INPUT);
pinMode(taster2, INPUT);
Serial.begin(9600);
}
void loop()
{
tasterstatus=digitalRead(links);

if (tasterstatus == HIGH)
{
digitalWrite(LEDblau, HIGH);
delay (100);
digitalWrite(LEDblau, LOW);
delay (100);
digitalWrite(LEDblau, LOW);
digitalWrite(LEDblau, HIGH);
delay (100);
digitalWrite(LEDblau, LOW);
}
else
{
digitalWrite(LEDblau, LOW);
}
}

void loop()
{
tasterstatus=digitalRead(rechts);

if (tasterstatuss == HIGH)

else

}

error message:

H:\Eigene Dokumente\Arduino\sketch_mar14a\sketch_mar14a.ino: In function 'void loop()':

Put all the code into one loop function

And get rid of the delays.

Check the spelling of the variables named in the error.
