If you want a macro to display a message after opening a form,where should you insert the MessageBox action?

A) As the first action in the macro
B) After the OpenForm action
C) As the last action in the macro
D) Before the OpenForm action

The MessageBox action should be inserted after the OpenForm action, as the message should be displayed after the form has been opened. Placing it before the OpenForm action would mean the message is displayed before the form is opened, and placing it as the first or last action may result in the message being displayed at inappropriate times during the macro's execution.
