I'm using Mangeto 1.9.1 and i'm trying to create a module for 50% discount from the grandtotal price.
I've made some things to the module but when i try to open my http://mymagento.com/checkout/cart/ i've got blank page bellow my main menu. Blank page where my cart items and total should be.
Take a look: https://i.stack.imgur.com/Y5Vtf.png
I've made this module by this answer: https://stackoverflow.com/questions/26831818/magento-issue-with-creating-a-custom-module/26840374#26840374
So here is what i've done:

And in app/code/local/VivasIndustries/PercentPayment/sql/percentpaymentatribute_setup/mysql4-install-0.1.0.php :
<?php
$installer = $this;
$installer->startSetup();
$installer->addAttribute("quote_address", "discount_total", array("type"=>"varchar"));
$installer->addAttribute("order", "discount_total", array("type"=>"varchar"));
$installer->endSetup();
And finaly i've made this:
In app/etc/modules/VivasIndustries_PercentPayment.xml :
<?xml version="1.0"?>
<config>
<modules>
<VivasIndustries_PercentPayment>
<active>true</active>
<codePool>local</codePool>
<version>0.1.0</version>
</VivasIndustries_PercentPayment>
</modules>
</config>
And that's all what i've done and i get this blank page with no error.
Can you please help me find the problem and fix it ?
*EDIT
WHen i remove:
public function getLabel()
{
return Mage :: helper('modulename') -> __('Discount');
}
Thanks in advance!
config.xml's global section:<helpers><percentpayment><class>VivasIndustries_PercentPayment _Helper</class></percentpayment></helpers>and create a Helper directory and put there Data.php with empty class like 'class VivasIndustries_PercentPayment_Helper_Data extends Mage_Core_Helper_Abstract {}'
