@CharlesMay 04.2007 — You'll need to do this with JavaScript but you have to be careful not to ruin things for those of us who do not use JavaScript. You have to disable the TEXTAREA with JavaScript, not with HTML otherwise it will never get abled. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<meta name="Content-Script-Type" content="text/javascript">

<script type="text/javascript">
onload = function () {
document.forms[0].foo.disabled = true;
}
</script>

<form action="some-script.pl">
<fieldset>
<input onclick="this.form.foo.disabled = !this.checked" type="checkbox">
<textarea name="foo"></textarea>
</fieldset>
</form>

Success!
