Look through the `vout` array. Find the object that matches your address. (Here, it's the only one.) The `n` value is your `vout`. You now have everything you need to create a new CPFP transaction.

When you take these steps, everything should look totally normal, despite the fact that you're working with an unconfirmed transaction. To verify that all was well, we even looked at the results of our signature before we saved off the information to a variable:
```
$ rawtxhex=$(bitcoin-cli -named createrawtransaction inputs='''[ { "txid": "'$utxo_txid'", "vout": '$utxo_vout' } ]''' outputs='''{ "'$recipient2'": 1.2985 }''')
