# Add a footer function to screen

Add footer functions to the details screen in your record screens using Mobile App Builder.

## Before you begin

Role required: admin

Footer functions are functions that users can by tapping a button at the bottom of a record screen. Use this option for functions relating to the record rather than data in a specific field. You can add functions to forms by creating a function instance in any details screen that is embedded within your record screen.

## Procedure

1.  Navigate to **All** > **System Mobile** > **Mobile App Builder**.

    The Mobile App Builder appears in a new browser tab and displays the application scope selection screen.

2.  Search for the application scope you're working in and then select the name of the application scope.

    The Mobile App Builder categories home screen displays.

3.  Select the **Screens** category and then select the record screen.

4.  Use the configuration tree on the left to find and select the details screen where you want to add a footer function.\[Omitted image "add-func-to-details-1.png"\] Alt text: Details screen within the Mobile App Builder configuration tree
