@TheBearMayNov 28.2008 — Here's something that should work in both environments...

<i>
</i>&lt;script type="text/javascript"&gt;
function checkLength(len, cnter, parnt){
if (len &gt; 255) {
alert ("Maximum length exceeded");
parnt.value=parnt.value.substr(0,255);
len = parnt.value.length;
}
document.getElementById(cnter).innerHTML= (len)+" characters used, "+(255-len)+" characters remaining";
}
&lt;/script&gt;

[code=html]
<textarea name="comments" rows="5" cols="60" onkeyup="checkLength(this.value.length, 'comlength', this)" ></textarea>
<br>
<span id="comlength" style="font-size:xx-small"></span>
[/code]
