Hi @Rspv
Here's how you can set a default value that updates every time your form loads from a different list:
1. **Unlock the Data Card**: In the PowerApps studio, select the form and then the data card you want to modify. In the properties pane on the right, click on the lock icon to unlock the data card.
2. **Modify the Default Property**: Select the TextInput control inside the data card. In the properties pane, find the 'Default' property.
3. **Write the Lookup Function**: In the 'Default' property, write the following formula:
Lookup(UserDefaultInfo, Email = User().Email).PhoneNumber
This formula will look up the 'UserDefaultInfo' list (or data source), find the record where the 'Email' field matches the current user's email, and return the 'PhoneNumber' field from that record.
Please note that 'UserDefaultInfo', 'Email', and 'PhoneNumber' should be replaced with the actual names of your data source, email field, and phone number field, respectively.
Also, make sure that the user has the necessary permissions to read the 'UserDefaultInfo' list.
