**Tell us what’s happening:**

Hi there,

I can’t seem to figure out why my algorithm is failing only for sumFibs(75024), but works for all the others inputs.

**Your code so far**

```
function sumFibs(num) {
let total = 0;
let a = 1;
let b = 0;
let temp;
while (total <= num) {
if ( a % 2 !== 0 ) {
total += a;
}
temp = a;
a += b;
b = temp;
}
return total;
}
sumFibs(75024); // I get 135721 as an answer, but it should be 60696.
```
