hi
theres some code below that I found somewhere that does this, it should do
what you need
the textbox below the textarea gives a countdown of characters left and
starts counting down as they type.

Almost, it is compared with formname.value.length like in the example
below. Doesn't work flawlessly (one can paste stuff into the field
without pressing a key), but it is a start.
<textarea name="text" onkeypress="return checkLength(this,500)">
<script language="JavaScript">
function checkLength(formfield,limit) {
if (formfield.value.length > limit) {
alert("Only " + limit + " characters allowed.");
return false;
}
}
</SCRIPT>
