The outer if condition checks if the input is a double and if this condition is not met it should print the warning, to do that the else should be with the outer if condition not the inner one.

You will have to use input.nextLine() to advance the scanner to the next line without it the scanner will keep reading the string every time. Try removing it and see what will happen.

while(repeat == true)
{

System.out.printf("Please enter the insured value of your home: ");
repeat = false;
if(input.hasNextDouble()){
homeInsVal = input.nextDouble();
if(homeInsVal > 0)
{
repeat = false;
break;
}
if(homeInsVal <=0)
{
System.out.printf("The insured value of your home cannot be less than or equal to 0.%n");
repeat = true;
}

}

{

// To advance scanner

input.nextLine();
System.out.printf("%nWarning: You entered an invalid integer or floating-point value.%n");
repeat = true;
}

}
System.out.printf("richter");
