Please post a link to the page on your site that contains the problematic code so we can check it out.

Not as good as the moderators can do on here, but nonetheless functional, and not using innerhtml. ....

This Also suppresses "NaN" errors.

parseFloat() is what you are looking for though. It converts strings to values.

<script type="text/javascript">
function addstuff()
{
function silentErrorHandler() {return true;}
window.onerror=silentErrorHandler;
first = parseFloat(document.getElementById('val1').value);
second = parseFloat(document.getElementById('val2').value);
third = parseFloat(document.getElementById('val3').value);
document.getElementById('result').firstChild.nodeValue = first + second + third;
if (document.getElementById('result').firstChild.nodeValue == 'NaN') 
{document.getElementById('result').firstChild.nodeValue = "";}
else
{document.getElementById('result').firstChild.nodeValue = first + second + third;}
}
</script>
One:<input type="text" id="val1" name="val1" onkeyup="addstuff();"><br>
Two:<input type="text" id="val2" name="val2" onkeyup="addstuff();"><br>
Three:<input type="text" id="val3" name="val3" onkeyup="addstuff();"><br>
<a id="result" name="result">&nbsp;</a>
