Customizing Recent Order Customer Dashboard in Magento

I'm trying to customize the Customer Dashboard recent order table. Currently, it is only showing Order ID, Date , Ship to, order total and status.

I'm trying to replace Ship to into product name. Below is my attempt. I'm getting this error "Fatal error: Call to a member function getProductName() on a non-object" I'm very new in magento development. Hope you guys can help.
