#### [Am trying to get normalized value that is extracted using duckling for duration but am facing this error](https://forum.rasa.com/t/am-trying-to-get-normalized-value-that-is-extracted-using-duckling-for-duration-but-am-facing-this-error/36858/62)

between line 425 and 426 set your flag nodedescription to True. And remove lines 428 and 429.

Of course! You can contact me via Telegram chat. My user is [@brunohjs](https://forum.rasa.com/u/brunohjs).

Good! Maybe someone has an idea.

In the shell I think not. Rasa shell is for the developer can test the chatbot. Perhaps in some channel it is possible, for example in the website channel. I never did anything like that, so I don’t know how to answer you.

### Technical Responses

1. Use `.csv` file is a good idea. To work with `.csv` files in python, you need to use the csv lib. This tutorial can help you:

In particular, I would use a .json file because of its structure {"key": "value"}, in this case {"drug name": "drug description"}, but it is subjective.

2. The dispatcher is called whenever a bubble needs to be printed. Do you want the names to be displayed in the same bubble? If so, you can use that variable `department_response`:
   ```python
   department_response = ""
   for k in department_data:
       department_response += f"{k[0]} {k[1]}\t"
   dispatcher.utter_message(department_response)
   ```
   You do not need to create a variable `department_response` just to store the response. 
   ```python
   dispatcher.utter_message(f"{k[0]} {k[1]}")
   ```

3. Store the duration the same way you did for the other slots.

4. The method `get_latest_entity_values()` does not return the normalized value. To get the normalized text, you should use `tracker.latest_message["entities"]` property and filter by the entity duration.

5. To show the normalized value:
   ```python
   data2 = entity_val["normalized"]
   dispatcher.utter_message(f"{data2["value"]} {data2["unit"]}")
   ```
   For Example, if user input is "2 hours", output will be "7200 seconds".

### Image Examples

To put the data you want in that slot, you need to do the logic within the slot’s validate method.
