Validate second dropdown selected option not to be equal with first dropdown selected value

octav 27 Sep, 2019

Hello,
Please can anyone advise exactly how to validate second dropdown selected option not to be equal with first dropdown selected value.
I have 2 dropdowns that get data from same read_data action
United Kingdom
France
Belgium
---
---
etc.

I need that if in both dropdowns is selected United Kingdom, to show message and not proceed to submit action (which is a redirect)
I would very much appreciate a step by step demo exactly for this case. Thanks.
