I am trying to filter the multiple choice options in a drop down field based on what is entered in a preceding drop down field. For instance, I have set the choices for Dropdown Field 1 to a and b, and in Field 2, the choices are set for a, b, c, and d. When choice a is selected in Field 1, my requirement is for Field 2 to only display choices a and b. If choice b is selected in Field 1, then I need Field 2 to display choices c and d.
