Im sure everything works , Ive tested my first if paragraph plenty it turns fine etc all I want to do is add some distance for my sensors, thats why I added the second if paragraph

Ive even taking those 2 else if statements out then theres still a issue

It must be with these lines

if(t2>127 && t2<300){
	if(t2<t1 &&t 2<t3){
		analogWrite(PWM1,250);
		analogWrite(PWM2,250);
	}
}
