**Tell us what’s happening:**

I am having problems understanding the lesson because, I am finding the lesson too difficult. Can someone give me a guide our a few tips how I can understand this? I already triied going back the previouse lessons for better understanding and w3schools but this one keeps being to difficult for me.

**Your code so far**

```
function testSize(num) {
// Only change code below this line
if ((num) <5) {
return = ("Tiny")
}
if ((num) < 10) {
return = ("Small")
}
if ((num) < 15) {
return = ("Medium")
}
if ((num) < 20) {
return = ("Large")
}
if ((num) >= 20) {
return = ("Huge")
}
return "Change Me";
// Only change code above this line
}
// Change this value to test
testSize(7);
```
