Up to line 57 you are using mysqli, after that mysql, possible problem there?

As mentioned, on page load, $firstparty does not exist, so testing it for values will throw an error.

As opposed to showing a message on page load, I'd use a zero-length string (''), so that you could use the html5 placeholder.

<?php
    $fp = (isset($firstparty) && !is_null($firstparty)) ? $firstparty : '';
?>

<td>First Party*:</td><td><input type="text" name="firstparty" value="<?php echo fp;?>" placeholder="Enter first party" /></td>

$firstparty is not defined? Can I see the rest of your code? You're theory is correct as you can do this:

<?php
   $firstparty = "Enter here";
?>

<td>First Party*:</td><td><input type="text" name="firstparty" value="<?php echo is_null($firstparty)? "":$firstparty;?>"/></td>
