When I run the following code, I get a UNIX timestamp for debugFeaturesLaunch, but not debugFeaturesLogin. Can someone see what I am obviously overlooking?

Thanks!


PHP Code:
// $_SESSION[lastLogin] uses dates in the format of 01-30-2012

$lastLogin strtotime($_SESSION[lastLogin]);
$_SESSION[debugFeaturesLogin] = $lastLogin;

$launchDate  "07-01-2012";
$launchDate strtotime($launchDate);
$_SESSION[debugFeaturesLaunch] = $launchDate;

if (
$lastLogin $launchDate) {
    
$campaign "Features";
    
$_SESSION[viewedCampaignToday] = "Yes";
