expanding form

is there a way to add a button to a form that when clicked it will add more input boxes like

<form>
<input type=”text” name=”q1″>
<input type=”text” name=”a1″>
<input type=”button” value=”Add Question” onclick=”add()”>

when clicked once it would

<form>
<input type=”text” name=”q1″>
<input type=”text” name=”a1″>
[b]<input type=”text” name=”q2″>
<input type=”text” name=”a2″>[/b]

clicked twice

<form>
<input type=”text” name=”q1″>
<input type=”text” name=”a1″>
<input type=”text” name=”q2″>
<input type=”text” name=”a2″>
[b]<input type=”text” name=”q3″>
<input type=”text” name=”a3″>[/b]

and so on.

When it is clicked submited, it sends a var cells=”3″
or cliked 1 var cells=”2″
so a loop can uncode the info

it is going to be a quiz page maker.
