**Tell us what’s happening:**

Why this method of finding prime number is not working.

**Your code so far**

```
function sumPrimes(num) {
let flag=0;
let a=[1,2,3];
for(let i=4;i<=num;i++){
for(let j=2;j<=i/2;j++){
if(i%j===0)
{
flag=1;
break;
}
}
if(flag==0)
{
a.push(i);
}
}
console.log(a);
return num;
}
console.log(sumPrimes(10));
```
