Multiple Text Boxes help

<html>
<head>

</head>

<body>

<select name="boxes" onChange="boxes()">
<option value="">choose</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
<script type="text/javascript">
function boxes(NumberOfBoxes){
for(i=0;i<NumberOfBoxes;i++){
boxes += "<textarea name='textbox[NumberOfBoxes]'></textarea>";
}
document.getElementById('textboxes').innerHTML = boxes;
}
</script>
<div id='textboxes'>

</div>
</body>

<select name="boxes" onChange="boxes()">

// boxes need one parameter "number" of textboxes
// u need to pass option value to it, e.g. boxes(2);
// u might try this boxes(this.value); - i'm not sure if that will work
// but u need to pass a value somehow

No good, well this line;

gave internet explorer an error (Object doesn't support this property or method), firefox just didn't do anything.

Any other ideas?

Fantastic! got it working, thank you very much (that saved me much hair pulling and headaches).
A further question would be how to reference the text boxes in the form-mailer php script. If I define each box

$textbox = ($_POST["textbox"]);
$textbox1 = ($_POST["textbox1"]);
$textbox2 = ($_POST["textbox2"]);

I get a result "Array,,,"

If I use $textbox["+i+"] = ($_POST["textbox["+i+"]"]);

I get nothing.

Any ideas on this part?

well actualy , i did allready answer your question :-)
fboxes function creates textareas as an array - look at names !!! of each box $textbox[1] ,$textbox[2] and so on well its no good practise (u should use $_POST['textbox'][1]) but it simplier to explain and to use
by the way if you need to know what is in the memory print it!!!
e.g.
[php]<?php
function echovariables($variable){
echo "<ul>";
foreach($variable as $k=>$v){
echo "<li>$k =>$v </li>";
if(is_array($v)){
echovariables($v);
}
}
echo "</ul>";
}
echovariables($_POST);//can be any variable
?>
[/PHP]

if you try it u ll see what you got
