This is a good first check, but I would never blindly trust any sort of
client-side data validation. This is just inviting hackers to have a
field day.

I agree with Joel. Using JavaScript to process on the client side is
fast and doesn't need to hit the CF server. I always
use this to check numeric value: ( I am sure many of you already know
how to do this, but I am posting it for those who
might not know.)
===========================
<script language="Javascript">
function checkfield()
{
if (isNaN(document.forms[0].phone.value))
{alert ("Sorry, but you must enter a numeric value.")
document.forms[0].phone.focus();
return false;
}
}
</script>
