14 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.
This check verifies that the user has selected exactly one option from the 'Account Type' section (Electronic Checking Account, Debit Card, or Both). Selecting none or more than one is invalid as the form specifies choosing one option. This is crucial for correctly setting up the account features and avoiding ambiguity in service provisioning. If validation fails, the form submission should be rejected with an error message prompting the user to select a single account type.
This validation ensures that precisely one account level (Platinum, Gold, or Silver) is selected. The account level determines the benefits and fee structure associated with the account, and the form requires one selection. A missing or multiple selection would prevent proper account classification and processing. Failure will result in an error asking the user to choose one and only one level.
This check confirms that at least one account owner has provided a signature in STEP 6. A signature is legally required to accept the terms of the Account Agreement and open the account. Without a signature, the application is incomplete and legally non-binding. If no signatures are present, the submission must be blocked.
This validation ensures that the 'Social Security or Tax ID Number' field for each account owner is entered in a valid format (e.g., XXX-XX-XXXX for SSN or XX-XXXXXXX for TIN). This number is critical for tax reporting and identity verification (KYC). An incorrectly formatted number can lead to processing delays and regulatory compliance issues, so the system should reject invalid formats and prompt for correction.
This check verifies that the 'Date of Birth' for each account owner is a valid date and that the calculated age meets the minimum legal requirement for opening a brokerage account (e.g., 18 years old). This is a fundamental compliance requirement to prevent establishing accounts for minors. An invalid date or an underage applicant will cause the application to be rejected.
This validation checks that the 'Name of Corporation' field in STEP 4 is only filled if the account is a corporate account and a debit card has been requested ('Debit Card' or 'Both' is selected in STEP 2). The form explicitly states this option is 'Available ONLY for corporate accounts'. This prevents individual account holders from incorrectly adding a corporate name, which would cause processing and card issuance errors.
