If anybody's having trouble posting code, don't worry about it. I've got this all figured out. But just FYI, it seems that the Wordpress commenting system filters out the script tag unless you replace the angle brackets with their & lt; style equivalents PS.

<SCRIPT TYPE="text/javascript">

function validate_form ( )
{
error = false;
error_string = "Please fill in these field(s):";

if ( document.contact.name.value == "" )
{
error = true;
error_string = error_string + " name";
}
if ( document.contact.email.value == "" )
{
error = true;
error_string = error_string + " email";
}
if ( document.contact.subject.value == "" )
{
error = true;
error_string = error_string + " subject";
}
if ( document.contact.comments.value == "" )
{
error = true;
error_string = error_string + " comments";
}

if (error == true)
{
alert (error_string);
}

return (!error);
}

</SCRIPT>

and don’t forget to change the form tag to include an onsubmit:

<form action="formmail.php" method="post" name="contact" id="contact" onsubmit="return validate_form()">
