problems using Javascript with CDML

I want to limit the number of characters a user can enter into a text area on a form. before i put any scripts on my form when the user edits the fields and clicks update, everything works well and the db fields are updated. However once i put the javascript to limit the number of characters in my textarea and then submit the form i get an "unknown error number 102". I know filemaker says this error is about incorrect links or field names but not in this case. Below is the javascript that i have used:

<head>

function limitText(limitField, limitCount, limitNum){

if (limitField.value.length > limitNum){

limitField.value = limitField.value.substring(0,limitNum);

}else {

limitCount.value = limitNum - limitField.value.length;

}

</script>

</head>

<body>

<table>

<tr>

<td class="style1"><div align="right">Contents</div></td>

<td><textarea name="limitedtextarea" onKeyDown="limitText(this.form.limitedtextarea,this.form.countdown,100);" onKeyUp="limitText(this.form.limitedtextarea,this.form.countdown,100);">[FMP-field:drivingsection]</textarea><br>

<font size="1">(Maximum characters: 100)<br>You have <input readonly type="text" name="countdown" size="3" value"100"> characters left.</font></td>

</tr>

Once i put this javascript in the textarea tag i get the error. Has anyone come across this before? Or know of another way i can limit a textarea....the ultimate goal is to limit it to a certain amount of characters based on contents of another field. I have just started with limiting it to 100 characters to test if it would work. Unfortunetly, it doesnt.

Any help much appreciated....

This is one that I use:

<tr><td>Establishment Description:<br>(Limited to 350 characters, approx 60 words)</td>

		<td colspan="2"><textarea name="estab_desc" cols="38" rows="4"><?php echo  $estab_desc ?></textarea></td></tr>



And the Javascript in the <head>

<script>

		function validate()

			{

			with (document.estabfm)

				{

				var subOK = true;

				sEstab_Desc = estab_desc.value;

				if (sEstab_Desc.length > 350)

						{ 

						subOK = false;

						alert ("The Description is " + estab_desc.value.length + " characters longnPlease shorten!!!");

						};

						

				if (subOK) { submit(); };

				};

			};

</script>

I use this in the <form> tag:

onsubmit="validate();return false;">

Remember that this:

name="limitedtextarea"

must be a name of one of the fields in your database.
