How do I add a custom magento payment option?

[ozonedeveloper]

I am trying to connect to a payment processor through magento.

This tutorial is what I am using as my guide:http://excellencemagentoblog.com/blog/2011/10/28/magento-create-custom-payment-method/

I get this error when I try to access payment options under Sales "Fatal error: Class 'Mage_Pay_Helper_Data' not found in C:\xampp\htdocs\magento\app\Mage.php on line 547"

I can post my system.xml and config.xml files if need be

Any help at all would be very much appreciated.

Thanks.

Its just not taking your namespace which you need to fix in the config.xml

Specify the helper in there for example

<helpers>
<modulename>
<class>Namespace_ModuleName_Helper</class>
</modulename>
</helpers>

Please see my config.xml file below and let me know your thoughts:

<?xml version="1.0"?>
<config>
<default>
<payment>
<pay>
<active>1</active>
<model>pay/pay</model>
<order_status>processing</order_status>
<title>Excellence Payment Method</title>
</pay>
</payment>
</default>
<modules>
<Pagayo_Main>
<version>0.1.0</version>
</Pagayo_Main>
</modules>

<global>
<helpers>
<main>
<class>Pagayo_Main_Helper</class>
</main>
</helpers>
</global>

<adminhtml>
<layout>
<updates>
<pagayoall module="PAGAYO_MAIN">
<file>pagayo_main.xml</file>
</pagayoall>
</updates>
</layout>
<acl>
<resources>
<admin>
<children>
<system>
<children>
<config>
<children>
<pagayostore>

</pagayostore>
</children>
