We did some zap tests on this note… we made six attempts to⚡zap this note, using your lightning address starting with "mr_greengold", over a period of about 1 hour. In each case, we found that your lightning address server did not respond correctly. (The failure point was when we did a GET request to your specified callback URL: https://getalby.com/lnurlp/mr_greengold/callback ). Your server did not produce an invoice, thus the zap failed. The error we got was "Invalid amount. Make sure the amount is within the range.". You might want to look into using a cloud-based Lightning node which is optimized for Nostr zaps, to get your zaps working.
