If you have multiple inputs relating to the same value, you can use bind:group along with the value attribute. Radio inputs in the same group are mutually exclusive; checkbox inputs in the same group form an array of selected values.

Add bind:group to each input:

<input type="radio" bind:group={scoops} name="scoops" value={1} />

In this case, we could make the code simpler by moving the checkbox inputs into an each block. First, add a menu variable to the <script> block...

ts
let menu = ['Cookies and cream', 'Mint choc chip', 'Raspberry ripple'];

...then replace the second section:

<h2>Flavours</h2>

{#each menu as flavour}
	<label>
		<input type="checkbox" bind:group={flavours} name="flavours" value={flavour} />
		{flavour}
	</label>
{/each}

It's now easy to expand our ice cream menu in new and exciting directions.
