+Description
+This client script in ServiceNow is designed to validate the format of a PAN (Permanent Account Number) card during form submission.
+By ensuring that the PAN card number entered adheres to the expected format, this script enhances data integrity and user experience. 
+If the entered PAN number is invalid, the script alerts the user, preventing form submission until a valid PAN number is provided.
+
+Key Features
+
+1. Format Validation: Checks PAN card format (5 letters, 4 digits, 1 letter).
+2. User Alerts: Provides immediate feedback for invalid entries.
+3. Submission Control: Prevents form submission with invalid PAN numbers.
+4. Customizable: Easily adjustable for different field names.
+5. Client-Side Efficiency: Quick validation without server delays.
+6. Data Integrity: Ensures only correctly formatted PAN numbers are accepted.
