Enter the tip.html text into a new Web page, then load the page in the browser to verify that it behaves as described.

Modify your page so that it contains a second text box, where the user can enter the tip percentage. For example, if the user entered 15 in the percentage box, the page would produce the same calculations . If the user entered 20 in the percentage box, however, the tip amount would be 20% of the check amount.

```
