You need to use javascript... what i usually do is add an onSubmit="return
validate();" to the form tag... the validate() being a function in the
<HEAD> part of the page. Validate would look something like this:

function validate()
{
	if (document.formName.textareaName.value.length > 30)
	{
		alert("Sorry. The maximum number of characters, 30, was exceeded on the
textarea. Please try again.");
		return false;
	}
	return true; // to get here, the above test must be OK
}

Hope that's OK,
Andrew Knox
