Customer Management System using ColdFusion: List, Update, and Delete

This ColdFusion script provides a user interface for managing customer records in a database. It includes functionality to display a list of customers, update their details, and delete records. The front page shows customer names with options to edit or delete each entry. When updating, a form is provided to change customer information such as address, balance, and credit limit. The script also handles error checking to ensure customer numbers are specified for updates and deletions.
