Can you post ALL your code, not just snippets.

Mike.
Edit, don't post a picture of your code, post the text between code tags.

#include "NewPing.h"
#define echoPin 7
#define trigPin 6
#define buzzPin 8
unsigned int dly=300;
NewPing distance(trigPin, echoPin, 500);
void setup()
{
    pinMode(buzzPin, OUTPUT);
   Serial.begin(115200);
}
void loop()
{
float cm=distance.convert_cm(distance.ping_median());
Serial.println(" Subject is ");
Serial.print(cm);
Serial.print(" cm away");
    noTone(buzzPin);
    while(cm<300)
    {
       unsigned int gap=(dly-cm)*50;
        tone(buzzPin, gap, 400);
    }
}

If the program doesn't compile, what's the error message?

tone ( pin, frequency, duration); It specifically says unsigned int, you are passing a float.. cast it to see if it fixes

tone(buzzpin, round(gap), 400); or.. tone(buzzpin, (int)gap, 400);

Where does it mention that in the error message?
