Question: I found bug in tag form. From this code:

```
<form>
<input type="text">
</form>

```

I type something in textbox and enter, Form is submit. But I rewrite code to this

```
<form>
<input type="text">
<input type="text">
</form>

```

I type something in textbox and enter again, Form isn't submit.

I have never met before. What happen? Someone can tell me.
Thank you for help or suggestion.

Answer: 
Example:

```
<input id="submit-button" type="submit" tabindex="110" value="Post Your Answer">

```

(look at the source of this page)

and specify some action in form field.
Name your inputs, or provide an id. How does the browser know how to post your data? It doesn't, so it cannot make an auto-submit on enter.
