Requiring Input If A Condition Exists

[SCW]

I want to require a secondary entry if certain input exists. Is there a way
to require the user to enter more information if they select that input?

SCW,

Yes, there is. You could use code on the Before Update event of your
form to check that the requirement has been complied with. Or you could
use a Validation Rule. To assist the user, you could use code on the
After Update event of the control for the first field, to toggle the
Visible property of a control for the entry of the secondary data,
according to the primary input.
