• • NOTE:** Click on the step/number to access the corresponding images.

• • [183]**. The **Person** ViewModel - the button **CarsIUsedToOwn** - does not function and can be removed. Let me explain its origin.

When we adopted the AutoPersonForm and named it Person, it initially worked as it pointed to the AutoFormPersonCarsIUsedToOwnMultiLink, which displayed the content of CarsIUsedToOwnMultiLink. Since then, we have regenerated the AutoForms, causing this action to lose its form, and a new form was created that the previous action is not connected to. Remove the button and the ViewModel action **MultiLinkCarsIUsedToOwn**.

• • [184]**. Add a ViewModelColumn and mark it as **Is Action**. Notice that it turns into a button.

• • [185]**. Name it `AddACarIUsedToOwn`.

• • [186]**. Create a ViewModelAction. Name it `AddACarIUsedToOwnAction`.

• • [187]**. Connect the button **AddACarIUsedToOwn** to the action **AddACarIUsedToOwnAction** by selecting it in the picker next to the Is Action checkbox.

• • 191**. When on the web, trying to add a new car I have owned, the Seeker for cars appears, but we want it displayed on top of the Person form.

• • [192]**. Go back to the **AddACarIUsedToOwnAction**, find the checkbox **Is Modal**, check it, and save. Test the web.

• • [193]**. A modal dialog OK button
