I have a form with two dropdown fields, DF1 and DF2. The dropdown choices in DF2

I have a form with two dropdown fields, DF1 and DF2. The dropdown choices in DF2 are dependent on the choice made in the dropdown DF1 field. The fields are editable and retain the intial selections if the form is returned for editing. On a return for editing, I need for the DF2 field to "reset" or dynamically "adapt" IF a change is made to DF1, thereby allowing a change to DF2, otherwise a “Choices not available in array” error message pops up. On the form you can manually avoid the error message by first changing DF2 to the placeholder value “Please choose from the following”, then changing DF1, but a user would not know that. Any ideas?...
