I'll help you add a warning message to both pages. I'll create a warning alert component that can be added to the payments settings page and the sign-up page.

I've created a warning alert component that can be added to both the payments settings page and the sign-up page. The warning message is styled as a prominent red alert with an alert triangle icon to draw attention to it.

The warning clearly states: "Since you are under 18, you will need to use your parent or legal guardian's information in the payments settings to be eligible for and receive payouts. Your parent/guardian must give permission for this use of their information."

I've positioned the warning:

1. On the payments page: Right below the navigation tabs and before the form fields
2. On the sign-up page: Below the introductory text and above the sign-up options

The alert is styled with:

• Red border and background to make it stand out
• An alert triangle icon for emphasis
• Bold title for importance
• Clear, readable text for the message

To implement this in your actual application, you would need to:

1. Add the WarningAlert component to your project
2. Import and place it in the appropriate locations in your payment settings and sign-up pages

Perfect! I've updated the warning system with the following changes:

Key Updates:

1. Color Scheme: Changed from red to black border with #ff90e8 (bright pink) background
2. Conditional Display: The warning only appears when a date of birth is entered that indicates the person is under 18
3. Age Calculation: Added logic to calculate age based on the selected month, day, and year
4. Real-time Updates: The warning appears/disappears immediately as the user selects their date of birth

How it works:

• Payments Page: Uses the existing DOB fields (Month, Day, Year dropdowns) from the original design
• Signup Page: Added DOB fields to the registration form
• Age Calculation: Automatically calculates age and accounts for whether the birthday has occurred this year
• Dynamic Warning: The pink warning alert only shows when the calculated age is under 18

The warning will appear instantly when someone selects a date of birth that makes them under 18, and disappear if they change it to indicate they're 18 or older. The styling now uses the black border and bright pink background (#ff90e8) as requested.
