# --description--

Ricordi che prima hai scritto una funzione per svuotare gli input dell'utente? Dovrai utilizzare quella funzione qui.

Aggiorna la dichiarazione di `currVal` in modo che sia il risultato della chiamata di `cleanInputString` con `list[i].value`.

# --hints--

La funzione `getCaloriesFromInputs` dovrebbe chiamare la funzione `cleanInputString`.

```js
assert.match(getCaloriesFromInputs.toString(), /cleanInputString\(/);
```

Dovresti passare `list[i].value` come parametro a `cleanInputString`.

```js
assert.match(getCaloriesFromInputs.toString(), /cleanInputString\(\s*list\[i\]\.value\)/);
```

Dovresti assegnare il risultato della chiamata di `cleanInputString` alla variabile `currVal`.

```js
assert.match(getCaloriesFromInputs.toString(), /currVal\s*=\s*cleanInputString\(\s*list\[i\]\.value\)/);
```
