# Dependent variables in actions

**Summary:** Ask follow-up questions in actions only when a previous answer matches, limit the initial language to those you support, and remove PII from training data by default.

**In short:** Build smarter, conditional action flows.

- The initial conversation language is now limited to the allowed languages set in your account. For example, if you support English and Dutch and opted for the AI to match the user’s browser language, when encountering any other language, the AI will default to the fallback language.
- Added the option to __remove PII from training data by default__ under privacy settings. Alternatively, you can toggle this on a per-source basis.
- We now support __dependent variables in actions.__ This means you can now ask a question to the user, but only ask it if a previous variable has a specific value. So for example, you can ask the user to select their company size from a dropdown list and based on what was selected ask for the company name in case of small companies, and ask for the phone number in case of big companies (so you can call them back).
- Added a setting to change the image of the live chat agent in the AI component.
