I am asking participants to rank order a set of four items through a series of dropdown boxes. Is there a way to create an error if someone ranks the same option twice? For example:
Rank 1: Item 1
Rank 2: Item 2
Rank 3: Item 1
Rank 4: Item 3
When the participant clicks to continue, this should throw an error message that the same Item was selected twice.
Thanks-MB
