Simple Provisioning Module Suspend/Unsuspend

[webbytech]

We are working on a simple module (or in my mind simple)

The following works in a standard php script so im not sure why the 2nd set of code doesn't work in WHMCS
Works in a regular PHP:
$vlan = "999";
$config1 = "set interfaces irb." . $vlan . " disable";
exec("ssh automation@xxx.xxx.xxx.xxx 'configure; $config1; commit; exit; exit;'");

Does not work in WHMCS module
function modulename_SuspendAccount($params) {

    $vlan = $params[‘customfields’]['VLAN'];
    $config1 = "set interfaces irb." . $vlan . " disable";
    exec("ssh automation@xxx.xxx.xxx.xxx 'configure; $config1; commit; exit; exit;'");
    $successful = '1';
    if ($successful == 1) {
        $result = 'success';
    } else {

    $result = 'Error: ' . $error;
    }
    return $result;
}

Anyone have any ideas why the WHMCS pieces doesn't work?
