Where is the $referrals

Okay, I'm slightly confused and pretty much peeved. I don't have time to delve into this code much more than I already have. I see on my profile on my site that I have 4 referrals. I have not made any link referrals anywhere so these referrals have to be coming from somewher.

1. Where is the existing code to add referrals to the database? I can write code from scratch to do what I WANT it to do, but I'd rather work within the vB framework if for no other reaosn so I don't get my wires crossed.

2. Theres a tempolate variable, $referrals, in my getinfo template. This is the portion that displays the referral count in my profile. This appears to be a reference to the getinfo_referrals template. So in THAT template, there is a call to $referrals again. WHERE is this variable defined?

Thanks for helping me sort this.

  // Get referrals
  if ($usereferrer) {
    if ($backcolor=="{firstaltcolor}") {
			$backcolor="{secondaltcolor}";
			$bgclass = "alt2";
		} else {
				$backcolor="{firstaltcolor}";
			$bgclass = "alt1";
		}
    $refcount = $DB_site->query_first("SELECT count(*) AS count
                                       FROM user
                                       WHERE referrerid = '$userinfo[userid]'");
    $referrals = $refcount[count];
    eval("\$referrals = \"".gettemplate("getinfo_referrals")."\";");
  } else {
		$referrals = '';
