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: 
you have to specify that a input submits the form

```
<input type="submit" type="text">

```

you might also want to define what happens when there is a submission
for example :

```
<form action="cgi-bin/formmail.pl" method="post">

```
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.
