# On Field Control Deactivate

> On Field Control Deactivate runs before a FlexiCapture field loses focus and lets your script change which field becomes active next via NewActiveControl.

## When it is launched

The script is launched before a field stops being active.

The field that is going to be activated next is passed to the script as an input parameter. This parameter can be changed.
