If this is a form in Form view (not Continuous or Datasheet), you can use
the Current event of the form to show/hide the extra field.
You will also need to use the AfterUpdate event of teh check box if you want
the field to appear/disappear immediately.
And you probably want to use the form's Undo event to examine the OldValue
of the yes/no field and restore the state.

I am creating a finance database from scratch. I have a yes/no field
in my table. I was wondering what can I do to display an extra field
when yes is clicked in this field. What events to use, what code?
