# Step 2. - Crafting Greetings

To extract and utilize this information effectively, the ***'Answer' node*** will leverage the *'smart extractor' function*. This function will be created within the entities panel, named *"Namex"* and configured as a smart function aimed at extracting the Full\_name from the user's response.

Now, let's proceed to customize our message nodes by leveraging the properties extracted using *"Namex"*:

* ***{Namex}*****:** Displays all properties along with their extracted values.
* ***{Namex\["name"]}*****:** Reveals only the customer's Name.
* ***{Namex\["name"]} {Namex\["surname"]}*****:** Shows both the Name and Surname of the customer.

You have the flexibility to choose the level of personalization you prefer. Remember to set our previously created ***'Function' node*** as the target node to establish a loop within the flow.

By integrating additional function nodes and connecting them to backend operations, we can develop a more robust user authorization flow based on the principles outlined in this guide.

1. Create an *'**Answer' node*** after the 'Message' node to progress with this step.
2. Name the **'Answer' node** and establish a new Entity named *"Namex"* as a smart function to retrieve the full\_name.
3. Proceed by creating a ***'Message' node*** after the ***'Answer' node*** and formulate a personalized welcome message.
4. Connect the target node of the ***'Message' node*** to the **'Function' node** at the beginning of the flow.

In [Step 6. ](https://docs.borndigital.ai/digital-agent/building-new-projects/..#step-6.-training-and-playing)observe the application of data from the *"Namex"* function across two rows. Feel free to experiment with other entities within the ***'Answer' node***.

Ensure to check and adjust the language settings in your project within the Project Settings. The extractor supports names predominantly from the domestic language group. For instance, certain names like **"Radovan"** might not be recognized as valid names in English language settings.

Entities within the ***'Answer' node*** function similarly to variables in other nodes. They serve the purpose of extracting specific information tailored to your use case.
