This is my form validation class:

```

Firstly, it asks for ds\_tipomodulo

 ![image](https://europe1.discourse-cdn.com/flex013/uploads/rasa/original/3X/3/4/34c5cb2a393eac49c459af920ac17a958316f338.png)

if ds\_tipomodulo == ‘NFE’, I “try” to set flag\_nfe to True. So if flag\_nfe is true, I want the bot to ask for valid\_rejeicao. If valid\_rejeicao is true, I want the bot to ask for nr\_rejeicao, if valid\_rejeicao is not true i want it to ask for ds\_analise.

If ds\_tipmodulo is not NFE, i want it to ask for ds\_tipoanalise, and finish.

The flow I want is something like this

I tried a lot but its not working properly yet. I’m new to Rasa and kinda new to Python too I’d really appreciate some help

You need to use a custom `FormValidationAction`, and implement that logic in the `required_slots()` method, as you are doing right now.

Can you tell me more about how exactly it’s not working? What is it doing that was not expected?
