System.out.println("Enter invoice number");
entry = input.next();
num = Integer.parseInt(entry);
while(num <= LOW || num >= HIGH)
{
System.out.println("Invoice number must be between " +
LOW + " and " + HIGH + "\nEnter invoice number");
entry = input.next();
num = Integer.parseInt(entry);
}
System.out.println("Enter sale amount");
