How do I clear off selected values on dropdowns?

Unknown

I have a form with 3 dropdowns on it. I would like to clear the selected values for the 2 following dropdowns when the first one is cleared or has its selection changed. What is the best way to accomplish this?

Hello,

This can be accomplished by doing the following:

1. Create a dataflow that outputs blank values under the same data names as your selected values in the dropdowns.
2. Set the trigger on this data flow to run on value change of your first dropdown.
