hi, I am currently experiencing a problem with drop-down menus and logical conditions. I have a first drop-down menu, when I select one of the options, a second drop-down menu appears, I select an option in this second drop-down menu, I have a third drop-down menu that appears. so far, no problems, but if I want to change my selection in the first drop-down menu, the second disappears well, but the third remains apparent and this is a big problem.
