The following script basically counts the characters in a text area and shows the number of characters on the fly. I need to have the combined total of four text areas limited to an amount and would like it to display the count as this script does. For example: a contact form that contains "Name", "E-Mail", "Phone" and "Message" fields that when combined can only reach 140 characters. The current form I am using unfortunately is not cross-browser compatible, so I am interested in correcting that as well, but am not sure how to go about it.
Here is a form that functions similar to what I would like to do.

Here is the code:
code:
<script language = "Javascript">
function taLimit() {
var taObj=event.srcElement;
if (taObj.value.length==taObj.maxLength*1) return false;
}
function taCount(visCnt) {
var taObj=event.srcElement;
if (taObj.value.length>taObj.maxLength*1) taObj.value=taObj.value.substring(0,taObj.maxLength*1);
if (visCnt) visCnt.innerText=taObj.maxLength-taObj.value.length;
}
</script>
<td width="267" height="560" align="left" valign="top"> <p> </p>
<?php
if ($_POST)
{
$name = $_POST['name'];
$email = $_POST['email'];
$comments = $_POST['comments'];
$message = "Message from $name ($email)\n\nPhone:$phone\n\nMessage:$message";
mail("info@yourname.com", "Test ESR", $message, "From: $name <$email>" );
echo "<p>Your Emergency Support Request has been submitted.<br>One of our representatives will contact<br>you shortly. Thank you. </p>\n";
}
else
{
?>
_Emergency Support Contact Form </span>
</p> <form action="<?= $PHP_SELF ?>" method="post">
<table width="265" border="0" cellspacing="0" cellpadding="1">

<td width="74" align="left" valign="top"><span class="body">From:</span></td>

}

I apologize in advance - I am new.
Thanks!
