The "Run Script" button should be located in your v0 project interface. Here's where to find it:

In your v0 project:

1. Look at the file tree on the left side of your screen
2. Find the scripts folder and expand it
3. Click on create-booking-tables.sql to view the file

4. Look for a "Run Script" button - it should appear either:

   • At the top of the file viewer
   • In the toolbar above the code
   • As a play button icon next to the filename

If you don't see the "Run Script" button:

• Try refreshing your browser
• Make sure you're viewing the SQL file (not just the folder)
• The button might be labeled as "Execute" or have a play icon ▶️

Alternative approach: If you still can't find the button, you can also copy the SQL content from the script and run it directly in your Supabase dashboard:

1. Go to your Supabase project dashboard
2. Navigate to the SQL Editor
3. Paste the SQL from scripts/create-booking-tables.sql
4. Click "Run"

Once the tables are created, your booking system will work with real database integration instead of the fallback data.

I've added duplicate filtering to ensure each service only appears once, even if the database returns duplicates. The fix includes filtering services by unique ID and added a cleanup flag to prevent double loading in React's StrictMode. This should resolve the issue of services appearing twice in the booking interface.
