Start by opening /pages/customer/addcustomer.html and reproducing the reported input issues in Chrome. Inspect the MRP, tax, discount, ID number, and product name fields. Done means the missing descriptions are present and tax and discount validation reject invalid percentage values, with the ID format documented or enforced as specified by the project.
