Hi @Ariel Eduardo Casiano García  -- Welcome to the Atlassian Community!

When you need to find the correct smart value for a field, please try this how-to article.  Basically you find an example issue and then call the REST API with a browser to list all of the possible fields.

I found that you can use de custom fields is this way: 

{{now.diff(issue.customField_10069).days}}+1

In the field configuration you can find the id
