<script>function setfoc() { document.f1.KeyWords.focus(); }

In the example above f1 is the name of the form and KeyWords is the name of the input textbox

In the body section:

<form name="f1" action="youraction" method="POST">
<input type="text" name="KeyWords" size="40" value="default text">
</form>

<script language="JavaScript">setfoc();</script>

$hostname = "www.domain.com.";
$dnstype = "MX";
$bValid = checkdnserr($hostname,$dnstype);

If using a DNS name then ensure the domain ends with the root domain qualifier (the “.”)

If the $dnstype is omitted or left blank the default check will be for an MX (Mail Exchanger) record.
