// Loads a blank page and displays something like "Hello Jane Doe! Your store credit balance is $150.25"
// If you don't already have the Magecredit Magento extension you can get it at www.magecredit.com

require_once('app/Mage.php'); //Path to Magento
umask(0);
Mage::app();

// Now you can run ANY Magento code you want

// Change 12 to the ID of the product you want to load
$_customer = Mage::getModel('customer/customer')
                ->setWebsiteId(1) // website ID
                ->loadByEmail('[email protected]'); // email address

$_balance = Mage::getModel('wf_customerbalance/balance')->setCustomer($_customer)->loadByCustomer();

// This line formats the amount using the currently loaded store's currency
$_amount = Mage::app()->getStore()->formatPrice( $_balance->getAmount() );

echo Mage::helper('core')->__('Hello %1$s! Your store credit balance is %2$s', $_customer->getName(), $_amount);
