Not sure what youre trying to do. Im assuming comare. so here it goes

if($first = NULL or
$last = NULL or
$gun = NULL or
$age = NULL or
$saying = NULL or
$email = NULL or
$phone = NULL or
$users = NULL or
$passs = NULL){

Then that should work but its not a good method.

When the user presses submit, you should check like this.

if(empty($username)) {
echo "Must enter a username";
$username = false;
} else {
escape_data($username);
$username = TRUE;
}

use the is_null() function

[code]if(is_null($var) || is_null($anotherVar))[/code]

You'll want to code your if statement like so:
[code]if(is_null($first) || is_null($last) || is_null($gun) || is_null($age) || is_null($saying) || is_null($email) || is_null($phone) || is_null($users) || is_null($pass))
{
    echo "Please fill in all fields!";
}
else
{
    //process form data
}[/code]
