Hi gys please help me :slight_smile:

void softInterr()
{
// Reading from first ultrasonic sensor
digitalWrite(triggerpin1, LOW);

S1= time0.034/2;
// Reading from second ultrasonic sensor
digitalWrite(triggerpin2, LOW);
delayMicroseconds(2);
digitalWrite(triggerpin2, HIGH);
delayMicroseconds(10);
digitalWrite(triggerpin2, LOW);

You obviously didn't read the old thread you chose to post in. If you had you would have posted the COMPLETE program and error messages, both in </> code tags.

You obviously have not posted the complete sketch. The error message you are seeing is typically caused by trying to define a function within another function, and often results from mismatched brackets or parenthesis in code prior to the line that generates the error message. If you are using the Arduion IDE, use Tools > Auto Format to auto format the code and the problem will usually be fairly obvious.
