In the text of the page, put "X character limit." Then $text = substr($text, 0, X)

You can also add the following as a guide to your form-submitters.

<input value="X" size="3" name="msgCL" disabled> <script language="JavaScript"> <!-- var supportsKeys = false function tick() { calcCharLeft(document.forms[0]) if (!supportsKeys) timerID = setTimeout("tick()",200) } function calcCharLeft(sig) { clipped = false maxLength = 200 //Change this. if (document.creator.signature.value.length > maxLength) { document.creator.signature.value = document.creator.signature. +value.substring(0,maxLength) charleft = 0 clipped = true } else { charleft = maxLength - document.creator.signature.value.length } document.creator.msgCL.value = charleft return clipped } tick(); //--> </script>

Hope this helps
