Code works, but move it to a class and it stops

Ok, I've been tearing my hair out over this trying to figure out what is going on. I'm at a loss, and probably just missing something REALLY simple, but I'm at a total loss.

I'm writing a little custom vba module for my guild.

I have 3 templates that I pull in

So I do something like this

PHP Code:

global $vbulletin;
eval('$home[$mods[\'modid\']][\'content\'] = "' . fetch_template('adv_progression_header') . '";');
$instances = $vbulletin->db->query_read( "SQL STUFF HERE" );
while ($instance = $vbulletin->db->fetch_array($instances))
{
    $img_name = $instance['image'];
    $name = $instance['name'];
    eval('$home[$mods[\'modid\']][\'content\'] .= "' . fetch_template('adv_progression_data') . '";');
} 


That works fine.

Now, trying to put it into a class

PHP Code:

class cls_progression
{
    var $theDB;
    function cls_progression( $DB )
    {
        $this->theDB = $DB;
    }
    
    function LoadInstances()
    {
        $instances = $this->theDB->db->fetch_array( $this->theDB->db->query_read("SQL STUFF HERE" ) );
        $iCount = $this->theDB->db->num_rows($instances);
        echo "iCount = $iCount";
        while ($instance = $this->theDB->db->fetch_array($instances))
        {
            $img_name = $instance['image'];
            $name = $instance['name'];
            eval('$home[$mods[\'modid\']][\'content\'] .= "' . fetch_template('adv_progression_data') . '";');
        }
    }

//call the class:
$progress = new cls_progression( $vbulletin );

$progress->LoadInstances(); 


the class doesn't work at all. I know it is called, but the echo returns just
"iCount = "

I'm horribly confused
