To share your project, click the "Publish" button in the top right corner of the screen. This will deploy your project to Vercel and give you a public URL you can share with anyone.
Alternatively, you can click the three dots menu in the top right and select "Copy Link" to share the current v0 chat directly.
Let me check the debug logs to see if there are any errors occurring when clicking the buttons.
The code looks correct and there are no errors in the logs. The buttons have onClick={() => setStep(2)} which should work. Let me add some debug logging to trace what's happening when clicking.
I've added debug logging to track button clicks. Please try clicking the buttons now and let me know if they work. If not, open the browser console (F12 or right-click > Inspect > Console tab) and tell me what messages appear when you click.
