Thank you very much for your kind reply, Paul. I tried it, but the
subform is still displaying every time - no matter what is chosen.The
dropdown box is called CarrierType.The subform called ForHireSubform
should only be displayed if "For-Hire" is chosen from the dropdown box
called CarrierType. Would you mind having a look at the attached form to
tell me where I'm going wrong? I'm an experienced programmer, but don't
have Livecycle or Javascript experience. Thank you very much.
