I had been written this code for my Arduino Uno line following robot, with 2 motor, 2 sensor and 1 L298N, and i can not fix the errors :cry:

#define motorkif 11
#define motorkib 10
#define motorkaf 9
#define motorkab 8

void setup() {
Serial.begin(9600);
pinMode(motorkaf, OUTPUT);
pinMode(motorkab, OUTPUT);
pinMode(motorkif, OUTPUT);
pinMode(motorkib, OUTPUT);
pinMode(12, INPUT);
pinMode(13, INPUT);
}

void loop() {
int sensorka = digitalRead(12);
int sensorki = digitalRead(13);

if((sensorka==LOW)&&(sensorki==LOW));
{
analogWrite(motorkaf, 0);
analogWrite(motorkab, 70);
analogWrite(motorkif, 50);
analogWrite(motorkib, 0);
}

else if((sensorka==HIGH)&&(sensorki==LOW));
{
analogWrite(motorkaf, 70);
analogWrite(motorkab, 0);
analogWrite(motorkif, 0);
analogWrite(motorkib, 50);
}

else if((sensorka==LOW)&&(sensorki==HIGH));
{
analogWrite(motorkaf, 0);
analogWrite(motorkab, 70);
analogWrite(motorkif, 50);
analogWrite(motorkib, 0);
}

else if((sensorka==HIGH)&&(sensorki==HIGH));
{
analogWrite(motorkaf, 65);
analogWrite(motorkab, 0);
analogWrite(motorkif, 65);
analogWrite(motorkib, 0);
}

else
{
digitalWrite(motorkaf, LOW);
digitalWrite(motorkab, LOW);
digitalWrite(motorkif, LOW);
digitalWrite(motorkib, LOW);
}

Serial.println(sensorka);
Serial.println(sensorki);
delay(100);
}

Please use code tags (</> button on the toolbar) when you post code or warning/error messages. The reason is that the forum software can interpret parts of your code as markup, leading to confusion, wasted time, and a reduced chance for you to get help with your problem. This will also make it easier to read your code and to copy it to the IDE or editor. If your browser doesn't show the posting toolbar then you can just manually add the code tags:
[code]``[color=blue]// your code is here[/color]``[/code]
Using code tags and other important information is explained in the How to use this forum post. Please read it.

Please always do a Tools > Auto Format on your code before posting it. This will make it easier for you to spot bugs and make it easier for us to read. If you're using the Arduino Web Editor you will not have access to this useful tool but it's still unacceptable to post poorly formatted code. I recommend you to use the standard IDE instead.

When you encounter an error you'll see a button on the right side of the orange bar "Copy error messages". Click that button. Paste the error in a message here USING CODE TAGS (</> button on the toolbar).

Get rid of the ; after each if

Yep, syntax is here:
