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">

```
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.
