Chaining If Else Statements : error while executing the code

Tell us what’s happening:
I think that my code should give “small” for num = 5 and num = 8 but it is giving errors. Can someone please help me to find my mistake?

Your code so far


function testSize(num) {
  // Only change code below this line
  if (num < 5){
    return "Tiny";
  } else if (num >= 5 && num < 10) {
    return "small";
  } else if (num >= 10 && num < 15) {
    return "Medium";
  } else if (num >= 15 && num < 20){
    return "Large";
  } else {
    return "Huge";
  }
  
  
  // Only change code above this line
}

// Change this value to test
testSize(7);

You have misspelled small. It should be “Small” with an uppercase S.
