I'm sorry, but as a text-based AI, I'm unable to view or refer to any attached screenshots. However, I can provide you with general steps to configure Twilio for P1 incidents in ServiceNow and troubleshoot common issues:

1. **Twilio Configuration in ServiceNow:**
- Create a Twilio account and get the Account SID and Auth Token.
- In ServiceNow, navigate to Twilio Integration > Configuration.
- Enter the Account SID and Auth Token from Twilio.
- Enter the From Phone Number. This should be a number that you've verified with Twilio.
- Click Test Configuration to ensure the settings are correct.

2. **Configure Notification:**
- Navigate to System Notification > Notifications.
- Create a new notification or modify an existing one.
- Set the When to send field to "Incident is P1".
- Set the Who will receive field to the appropriate user or group.
- Set the What it will contain field to the desired message.
- In the How to send field, select "Twilio SMS".

3. **Troubleshooting:**
- If you're getting an error when trying to send an SMS, it could be due to several reasons:
- Incorrect Twilio credentials: Double-check your Account SID and Auth Token.
- Unverified phone number: The From Phone Number must be a number that you've verified with Twilio.
- Network issues: Ensure that your ServiceNow instance can reach Twilio's servers.
- Notification configuration: Make sure the notification is set up correctly.

4. **Testing:**
- You can test the configuration by creating a P1 incident and checking if an SMS is sent.
