On a form I have a combo box that lists counties. My next box list townships that are in the listed counties. Is there a way to limit the list you see in the 2nd box to only show you what townships are in the county that you selected from the first box? What I am trying to accomplish is if someone picks "Jackson" from drop down box one, then when they click on drop down box 2..all that they see are those townships for Jackson county.
