I'm new to magento. here I have created custom module to add custom tab on customer information in admin panel. for that I have written following code. but it's returning an error. Any how here I'm not creating field to save the creditlimit attribute i will create after it's working.
Error: Class 'Mage_Adminhtml_CustomerController' not found.
my code is:
