Dear Magento Support Team Member
I want to completely remove the last name field from the magento onepage checkout page. I just want to keep the first name and need it to be validated.
I have edited the app/design/frontend/"My Theme"/"My Theme"/template/checkout/onepage/billing.phtml and removed other irrelevant fields like fax number etc. But from this file, when i remove the name fieldset of name, it removes both the text boxes of first name and last name. However i only want to remove the last name and keep the first name box.
Is there any file, from where i can redefine this fieldset of name and remove the last name property. Please provide the step by step procedure, as i am new to magento coding.
